Melting point of graphite powder
WebUse The resistance value of graphite powder will be different in different materials and environments. Due to its special structure, graphite has the following special properties: 1) High temperature resistant type: the melting point of graphite is 3850±50°C, and the boiling point is 4250°C. Web11 apr. 2024 · 1) High-temperature resistance: the melting point of graphite is 3850 ± Even if it is burned by a high-temperature arc, the weight loss and coefficient of thermal expansion are very small. The strength of graphite increases with the increase of temperature. At 2000 ℃, the strength of graphite is doubled.
