Application of graphite powder

Pulished on Aug. 24, 2019

Application of graphite powder shared by China graphite electrode supplier.

China graphite powder is soft, black gray; Greasy, can contaminate paper. The hardness is 1~2, and increases to 3~5 along the vertical direction with the increase of impurity. It is one of the most temperature-tolerant minerals when its melting point is above 3000℃ in isolation of oxygen. At room temperature, graphite powder is stable in chemical properties, insoluble in water, dilute acid, dilute alkali and organic solvent. Materials with high temperature conductivity, can be used as refractory materials, conductive materials, wear-resistant lubrication materials, xinruida graphite powder carbon content is generally more than 99 percent, sulfur content and ash content is low, often used in the production of carburizer, smelting industry.

Amorphous graphite powder for sale 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. Due to its special structure, xinruida high purity graphite powder has the following special properties:

Graphite Powder

High temperature resistant: graphite melting point is 3850±50℃, boiling point is 4250℃, even after ultra-high temperature arc burning, weight loss is very small, thermal expansion coefficient is very small. The strength of graphite increased with temperature, and doubled at 2000℃.

Electrical and thermal conductivity: the conductivity of graphite is one hundred times higher than the general non-metallic ore. The thermal conductivity is higher than steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature, even at very high temperature, graphite becomes an adiabatic body.

Lubricity: the lubrication performance of graphite depends on the size of graphite scales, the larger the scale, the smaller the friction coefficient, the better the lubrication performance.

Chemical stability: graphite has good chemical stability at room temperature, acid, alkali and organic solvent corrosion resistance.

Plasticity: graphite has good toughness and can be joined into very thin sheets.

Thermal shock resistance: graphite at room temperature when used can withstand drastic changes in temperature without damage, temperature abrupt change, the volume of graphite does not change, will not crack.
