Graphite powder soft, black gray;Greasy feeling, can pollute the paper.The hardness is 1~2, and it increases to 3~5 with the increase of impurity along the vertical direction.The specific gravity was 1.9~2.3.Under the condition of oxygen isolation, its melting point is above 3000℃, and it is one of the minerals that can withstand high temperature.At room temperature, the chemical properties of graphite powder are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents;Reacts with oxygen at different temperatures to produce carbon dioxide or carbon monoxide;Only fluorine can react directly with elemental carbon in halogens.Under heating, graphite powder is easily oxidized by acid.At high temperatures, it also reacts with many metals to form metallic carbides, which can be smelted at high temperatures.The application of graphite powder mainly shows that graphite has good chemical stability.The specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity, low permeability and so on. It is widely used in the manufacture of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters and pump equipment.Widely used in petrochemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.Graphite can be used as pencil refills, pigments and polishes.After special processing, graphite can be made into various special materials for use in relevant industrial sectors.
Henan Xingxing has been committed to the production of metallurgical refractory materials for many years, the products are complete, including ferrosilicon, calcium silicon, slag silicon, metal silicon and other metallurgical materials, and the quality of graphite powder produced is good, the price of graphite powder is low, the market demand is large, has been recognized by new and old customers and a large number of purchases, friends in need please consult the company's home page：https://www.alloyssi.com/
