Who can give a detailed description of the degree of volatility of graphite at various temperatures?
Graphite is a nonmetallic mineral with high temperature resistance and conductivity. Graphite products made of graphite are widely used in metallurgy, smelting and vacuum furnaces
The melting point of graphite is 3850 + 50 DEG C, and the boiling point is 4250 DEG C. Even though the arc is burnt by ultra high temperature, the weight loss is very small, and the coefficient of thermal expansion is very small
General use temperature of 1600-1800 degrees Celsius, 3000 degrees Celsius for softening temperature, generally high temperature volatile is inside the impurities, not graphite itself. I do graphite, has not seen graphite volatilization
