The use of graphite products----as a refractory material

The use of graphite products is much higher than we expected, so what are the uses of graphite products we know so far? 

Used as a refractory material

Because carbon and graphite products can withstand high temperature and have good high temperature strength and corrosion resistance, many metallurgical furnace linings can be built with carbon blocks, such as the bottom, hearth and bosh of ironmaking furnaces, ferroalloy furnaces and calcium carbide furnaces. Lining, the bottom and sides of the aluminum electrolytic cell. Many crucibles for smelting precious metals and rare metals, graphitized crucibles for melting quartz glass, etc. are also made of graphitized blanks. Carbon and graphite products used as refractory materials should generally not be used in oxidizing atmospheres. Because, no matter whether carbon or graphite is ablated quickly under the high temperature of oxidizing atmosphere.
