High Purity Good Conductivity Graphite Heat Sink for Electrolysis
High Thermal Conductive Carbon Graphite Block For Heat Exchanger
React with oxygen at different temperatures to produce carbon dioxide or carbon monoxide; In halogens only fluorine can react directly with the elemental carbon; Under heating, graphite powder is more easily oxidized by acid. At high temperature, it can also react with many metals to form metal carbides, which can be smelted at high temperature.

Graphite powder is a chemical reaction is very sensitive material, in a different environment resistivity he will change, also is his resistance to change, but one thing is not changed, the graphite powder is one of the very good non-metallic conductive material, as long as the object of the insulation inside guarantee graphite powder uninterrupted, like a thin line, also will be powered, but, how much is the resistance value, this value is not an accurate number, because the thickness of graphite powder, graphite powder used in different materials and the environment resistance will be different.
Low Conductivity Anode Graphite sheet For Battery
Due to its special structure, graphite has the following special properties:
1) high temperature resistant type: graphite melting point is 3850 + 50 ℃, boiling point is 4250 ℃, even by the ultra high temperature arc ignition, weight loss is small, thermal expansion coefficient is small. Graphite with temperature increase and strengthen the intensity, at 2000 ℃, the intensity of graphite double.
2) conductivity and thermal conductivity: the conductivity of graphite is 100 times higher than that of general non-metallic minerals. The thermal conductivity of steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature. Even at extremely high temperature, graphite becomes an adiabatic.

3) lubrication: the lubrication performance of graphite depends on the size of graphite scales. The larger the scale, the smaller the friction coefficient and the better the lubrication performance.
4) chemical stability: graphite has good chemical stability at room temperature and can resist acid, alkali and corrosion of organic solvents.
5) plasticity: graphite has good toughness and can be connected into very thin sheets.
6) thermal shock resistance: when used at room temperature, graphite can withstand drastic changes in temperature without damage. When the temperature changes abruptly, the volume of graphite does not change much and no cracks will occur.
