- The melting point of high temperature resistant graphite is 3850℃±50℃, and the boiling point is 4250℃. Even if it is burned by ultra-high arc, the loss of quality is very small, and the coefficient of linear expansion is also very small. The strength of graphite increases with the increase of temperature. At 2000 ℃, the strength of graphite doubles. Magnesia-carbon bricks for converters.
- Electrical and thermal conductivity. The conductivity of graphite is twice as high as that of ordinary non-metallic minerals. The thermal conductivity exceeds that of metal materials such as steel, iron, and lead. Thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite acts as a thermal insulator.
