⇒ "It was very scary to watch these shots, children's crying, screams, I'm afraid to even imagine what horror the passengers experienced. Of course, it is very interesting who caused this accident, for sure the blow was very strong, since the bus fell on its side, the most important thing is that there would be no casualties, but there will probably be many victims. More and more often, accidents related to tourist buses are shown on TV, sometimes it seems that this type of transport is the most dangerous for travel, in contrast to the same planes."

⇒ "This is of course terrible, I hope no one was hurt. But judging by the construction waste around the school, repairs are underway there, or this very roof is being blocked. The only strange thing is that the children are in the building, at least those who filmed everything, but perhaps the wing from which the roof fell off is closed for visits. But, unfortunately, we have already forgotten how to be surprised. Now there is such an attitude to construction that you can only wonder how we are still alive. It seems that there were no sensible fasteners at all, since it was not even blown away by a strong wind. Hopefully the contractor will be punished."

⇒ "The uniformed girl in the foreground is acting strangely. In the beginning, it seemed as if she even smiled. Her inaction amazes me. Or he simply does not know what to do or has not yet figured out what to do. An eerie sight. I'm surprised that some of the passengers still had the strength to shoot something. Or the person suffered the least. Probably one of the first to leave the plane. I also noticed a man with a suitcase. Did someone have time to stretch out their luggage. Or is it a passenger on the wrong plane?"

⇒ "Such videos can be watched only at home, so as not to get depressed) Lying on the couch, listening to the sound of the waves, drinking beer or sweet cider (whoever)), you can relax and imagine yourself far away on the beach, swaying on the waves. And if you set endless scrolling, then you can fall asleep and wake up to the sound of waves. Isn't it an idea for a good rest? In this case, the screensaver, of course, does not play a special role here, more sound effects. The sound of the sea sounds very relaxing and pleasant, you can't argue with that."

⇒ "Zhenya's work is great again, really strong and true. I looked at this review with great pleasure, got a lot of impressions. As always, the review is informative and funny enough. I’m wondering, directors, when they create films, they don’t notice their mistakes and mistakes at all, well, this is absolutely tough. Evgeniy found so many mistakes and shortcomings without any problems. Russian cinema is in a deplorable state. Many thanks to Evgeniy, his works are great. Many thanks for the lack of advertising."

Many adore the beauty of the Universe so much that in every possible way they try to be closer to it both in real life and in computer games... The Warframe Universe offers such a chance. In the role of the main character Tenno, you plow the vastness of endless space on your ship, simultaneously destroying opponents, improving your combat skills and completing interesting quests for which they provide valuable resources. This article will focus on such a resource as argon crystals and where to get them. It is worth recalling that the resource is obtained more easily in a group than alone.

What are argon crystals for?

Argon, like other resources obtained by the character during the game, is used to craft various devices: weapons, costumes, quest items. Argon is widely used, but its production is very problematic. Moreover, if you put argon in your inventory, then after a few days it will safely disappear.

In the real world, argon crystals also exist, but only at a temperature of -180 ° C degrees, at a higher temperature the crystals instantly turn into gas. Perhaps the developers decided to make a direct reference to a real natural substance.

Where to farm argon crystals

Argon crystals are not only a rare resource, but also difficult to obtain, because they can only be found in the abyss. Fun fact: argon does not disappear on the territory of the abyss, only outside of it, which already hints at the extreme climatic conditions of this location. To find out how much is left before the disappearance of argon from your inventory, you need to go to "Components", there will be displayed the time until decay.

Finally

We hope this article helped you in your search for such a rare material as argon. It is worth recalling that the amount of the extracted substance will be much greater if you participate in a group or use amplifiers for the drop of items and experience, since not everyone will like running such a long distance every time.

A person constantly encounters crystals, or frozen polyhedrons. Moreover, apart from natural minerals, exists crystals grown by artificial means. You can even grow a small crystal (for example, salt) at home. But it is possible to create a crystal with the desired properties only with the help of special equipment. This primarily concerns single crystals that do not occur in nature. To obtain them, you need a number of conditions, including a certain environment.

In 1892, the French explorer Auguste Verneuil discovered a simple and available method growing crystals using hydrogen and oxygen without a container. Using Verneuil's technology, it was possible to obtain a synthetic ruby ​​of 20-30 carats in 2-3 hours. Since 1902, his method has been used in jewelry industry and instrumentation, first in France, and then in other countries. But the method had a number of significant disadvantages associated with the use of a redox medium to obtain crystals. First, the crystals grown were of low quality. Secondly, it was only possible to work with certain types of materials. Finally, large losses of the final product were identified.

Nevertheless, the Auguste Verneuil method was actively used until the early 50s. Then it was improved. It began to be used as a medium for obtaining crystals. The choice fell on this bummer gas because of its property not to enter into a chemical reaction with other substances. Three gas streams were passed through the quartz tubes of the burner. The main one was a charged flow of argon. The powder of the initial substance fell into the crystallizer on the surface of the growing crystal. Thanks to the inert atmosphere created by argon, it was possible to obtain single crystals of very high purity. In addition, the range of materials from which they could be grown has significantly expanded.

In 1916, Polish chemist Jan Czochralski discovered a new method for growing single crystals in an argon atmosphere. Using his method, it was possible to work with large volumes of source material and obtain not only artificial gems but also semiconductors (such as silicon and germanium).

To grow a single crystal by the Czochralski method, a special installation is required. It consists of a furnace, a crystal pulling mechanism, a device for regulating the atmosphere, and a control unit. Such an installation can simultaneously load from 12 to 30 kg of raw material. Argon at atmospheric or elevated pressure enters the chamber where the molten metal is located. At the same time, the neutral environment of argon not only makes it possible to obtain high quality material, but also reduces the intensity of its evaporation. A dummy bar is then introduced into the purified melt and an ingot of a given size is drawn. Certain requirements are also imposed on the quality itself. It should be of the highest possible purity and contain only negligible amounts of moisture and impurities, including hydrocarbons.

Scientific thought does not stand still, therefore, no matter how good Czochralski's method is, it has improved over time. In particular, O.A. Remizov and N.M. Karavaev proposed to change the argon consumption and pressure at different stages of the silicon crystal growth process. The result is an even higher purity ingot with a minimum carbon content.
YL Sternik and IN Zaitsev went even further. They came up with their own apparatus for growing single crystals, in particular sapphire, in a neutral atmosphere. In this installation, argon is needed to accelerate the cooling process of an already finished crystal. It is fed into the chamber through a shut-off valve installed on the vacuum system.

And, finally, one cannot fail to mention the method of obtaining artificial crystals from the gas phase. Argon also plays an important role in this process. It is in the flow of this noble gas that the crystallization of the substance occurs, which enters the growing ingot in the form of vapor. This method has become widespread, since it can be used to obtain both crystals of large mass and thin plates and films.
As you can see, growing artificial crystals using argon has a lot of undeniable advantages.

Firstly, its cost is low; therefore, it is profitable to use argon on an industrial scale. So, to obtain 1 kg of artificial crystals, about one and a half thousand liters of argon are required. It is clear that it would be simply unprofitable to use expensive gas.

Secondly, due to its inertness, it does not enter into a chemical reaction with other substances. As a result, crystals grown in an argon atmosphere will not contain foreign impurities.

Thirdly, it turns into a liquid and crystallizes at a very low temperature, so it can be used during processes that require deep cooling (down to -185 degrees).

Finally, an efficient system for the chemical purification of argon has been developed. And to obtain a high-quality single crystal, only the highest grade gas is needed.
It should be noted that DP Air Gas is one of the leading suppliers of high purity argon. Every manufacturer of artificial crystals in Ukraine, as well as in the CIS and the European Union, will undoubtedly find argon for themselves. required quality among those offered by the company.

Interestingly, modern industry only produces argon in a liquid and gaseous state. But it turns out that it can not only be used as a medium for the production of synthetic crystals, but also itself has the ability to form crystals, called clathrates, or crystalline hydrates. They are cubic in shape and contain 46 water molecules in their structure.

When clathrates are formed, molecules of substances that have cavities in their lattices accept molecules in them. For the first time this phenomenon was described by the French chemist Villard in 1896, when he carried out the crystallization of water in an argon atmosphere. Ar 6H2O has been studied in most detail to date.

In 2000, Finnish scientists discovered another inclusion compound - argon hydrofluoride HArF. But scientists have not yet succeeded in achieving the stability of this hydrate.
In addition, spectral analysis gives researchers reason to believe that it is possible to obtain another compound - CU (Ar) O. It will be a combination of argon, uranium and hydrogen fluoride.
