August 21, 2023

1Smoothness: The smooth function of graphite is similar to molybdenum disulfide, the friction coefficient is less than 0.1. Its smooth function varies with the size of the scale, the better the degree of graphitization, the smaller the friction coefficient, the better the smoothness.

2Special thermal shock resistance function: graphite has outstanding thermal shock resistance function, that is, when the temperature changes suddenly, the coefficient of thermal expansion is small, so it has outstanding thermal stability, when the temperature is hot and cold change, there will be no cracks.

3Thermal conductivity and electrical conductivity: graphite has excellent thermal conductivity and electrical conductivity. Compared with the general data, its thermal conductivity and electrical conductivity are appropriately high. 4 times higher than stainless steel, 2 times higher than carbon steel, 100 times higher than the general non-metal.

4High temperature resistance: graphite is now known as one of the high temperature resistance materials. It has a melting point of 3850℃±50℃ and a boiling point of 4250℃. It is in the ultra-high temperature arc of 7000℃ for 10 S, the loss of graphite is small, according to the weight of graphite lost 0.8%. It can be seen that the high temperature resistance of graphite blocks is very outstanding.

5Chemical stability: graphite has outstanding chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.

Due to the outstanding high temperature resistance of graphite blocks, special thermal shock resistance, thermal conductivity, electrical conductivity, smoothness and chemical stability and widely used in metallurgy, machinery, electrical, chemical, textile and other occupations.
