Amorphous graphite ( Powder And Briquette)
also known as microcrystalline graphite powder, amorphous graphite powder, and black lead powder, belongs to cryptocrystalline graphite. After multiple explorations by geological departments, China currently has 2 billion tons of earthy graphite, which is the world's largest reserve. The vast majority of microcrystalline graphite is graphite carbon, with a hard gray color, metallic luster, soft texture, MoSe hardness of 1-2, the specific gravity of 2-2.24, stable chemical properties, not affected by strong acids and bases, low harmful impurities, low iron, sulfur, phosphorus, nitrogen, molybdenum, hydrogen content, and high-temperature resistance, heat transfer, conductivity, lubrication, and plasticity. It is widely used in casting, coating, batteries, carbon products, pencils, pigments, fire-resistant materials, smelting, and carburizing agents, Casting protective slag, etc. Specification: It is divided into two categories: "WT" - with iron requirements (commonly known as "electric carbon") and "W" - without iron requirements (commonly known as "casting"). The main products include graphite balls, graphite powder, graphite particles, graphite sand, and carburizing agents. According to the fixed carbon content, it is divided into 8 levels: 50, 65, 70, 75, 78, 80, 83, 85, and 88. The fineness of graphite powder is divided into 45, 75, and 150 μ m (equivalent to 325 mesh, 200 mesh, and 100 mesh, respectively).
