Graphite Powder Resists High Temperature
Graphite powder is a kind of carbon material, its main component is carbon. Because of the chemical stability of carbon, graphite powder shows excellent performance at high temperature.This article from the structure, physical properties and thermal properties of graphite powder, such as multiple point of view, to explain why graphite powder can resistance to high temperature.

Physical properties of graphite powder
Graphite powder has some special physical properties, which are also important reasons for its high temperature resistance.
(1) Low expansion coefficient
Graphite powder has a very low coefficient of expansion, that is, when the temperature changes, its volume changes very little. This property makes the graphite powder will not expand at high temperature, so there will be no deformation or crack phenomenon.
(2) High strength and high stiffness
Graphite powder has high strength and stiffness, which allows it to remain stable at high temperatures. At the same time, the graphite powder's high strength and stiffness also make it able to withstand the high temperature environment of the force, without deformation or damage.
(3) Good thermal and electrical conductivity
Graphite powder has good thermal and electrical conductivity, which enables the graphite powder to effectively transfer heat and current at high temperature, thus maintaining stable performance.

The thermal property of graphite powder is one of the important reasons for its high temperature resistance.
(1) High melting point and high thermal stability
Graphite powder has a very high melting point of about 3800℃, which allows it to maintain stable properties at high temperatures. At the same time, graphite powder is also very high thermal stability, will not be affected by oxidation or chemical reactions at high temperatures.
(2) Good thermal conductivity
Graphite powder has good heat conductivity and can effectively transfer heat at high temperatures. This property enables graphite powder to be used as a thermal management material in high-temperature components, thereby maintaining the component's stable performance.
