Chemical properties of graphite and carbon materials

Carbon materials are chemically inert in non oxidizing media. Under normal temperature and pressure, no chemical changes will occur. Except for long-term immersion in nitric acid, hydrofluoric acid, or in fluorine, bromine, and other strong oxidizing atmospheres, interlayer compounds will slowly form. It is not corroded by other acids, bases, and salts, and does not interact with any organic compounds. There is no significant oxidation phenomenon of graphite within 450 ℃ in the air. It only reacts with water vapor above 700 ℃ and with CO and CO2 above 900 ℃. The temperature at which graphite produces carbides with certain metal and oxide powders is mostly above 1000 ℃.The chemical reactions of carbon materials can be divided into the following three types:(1) Gasification reaction and high-temperature oxidation reaction;(2) Solid solid reactions with metals, ceramics, etc;(3) Formation reaction of interlayer compounds.

What issues should be paid attention to when using graphite crucibles

Graphite crucibles have a wide range of uses in the metallurgical industry, and their main function is to hold various liquid metals. As a metallurgical manufacturer, it is necessary to use graphite crucibles, otherwise there may be some problems in later production and use.Although graphite crucibles are of good quality and not easily damaged, they should also be handled with care. Falling or bumping from high altitude may not have a significant impact on its quality, but if it continues to do so for a long time, it may crack or even break. After this situation occurs, there is no way to remedy it, and we can only replace it with a new one.2. Graphite crucibles are prone to moisture, and the product will become soft after being affected by moisture. When struck by some impactful objects, it will deform. And once water enters the graphite crucible, it will affect the raw materials contained inside, causing dilution of the raw materials, and even causing some chemical reactions to furt
