Graphite plate has the characteristics of high body density, low resistivity, oxidation resistance, corrosion resistance, high temperature resistance, and good electrical conductivity.

1. High-purity graphite, Graphite with a graphite content of more than 99.9% is called high-purity graphite. Has excellent electrical conductivity, thermal conductivity, pressure and corrosion resistance, expansion system

Small number, good self-lubricity and good processing performance.

2.Good chemical resistance; can be used in various chemical reaction crucibles, test tubes, etc.

3.High thermal conductivity and thermal stability; various high temperature resistant products such as molten gold and molten silver

4.Sufficient mechanical strength and impact resistance;

5.Easy to machine, can be processed into various geometric products according to requirements.

6.Graphite has the following special properties due to its special structure:

6.1. High temperature resistance type: the melting point of graphite is 3850 ± 50 ℃, and the boiling point is 4250 ℃.

6.2 The expansion coefficient is also small. The strength of graphite increases with temperature. At 2000 ° C, the strength of graphite doubles.

 6.3 Electrical and thermal conductivity: The electrical conductivity of graphite is 100 times higher than that of general non-metallic ore. Thermal conductivity exceeds metal materials such as steel, iron, lead. Thermal system

6.4 The number decreases with increasing temperature, and even at extremely high temperatures, graphite becomes a thermal insulator.

 6.5 Lubricity: The smaller the friction coefficient, the better the lubrication performance.

6.6 Chemical stability: Graphite has good chemical stability at room temperature, and is resistant to acid, alkali and organic solvents.

 6.7 Thermal shock resistance: graphite can withstand severe temperature changes without damage when used at normal temperature. When the temperature changes suddenly, the volume of graphite changes.It is small and does not cause cracks.
