- Amorphous graphite, also known as microcrystalline graphite, commonly known as black lead powder. The color is gray black or steel gray, has a certain metallic luster, has a slippery feel, easy to dye hands, stable chemical properties, has good heat transfer and electrical conductivity, high temperature resistance, acid and alkali resistance, corrosion resistance and oxidation resistance
- Amorphous graphite is widely used in foundry coatings, oil field drilling, battery carbon rods, steel, foundry materials, refractory materials, dyes, fuels, electrode pastes, and used as pencils, electrodes, batteries, graphite emulsions, desulfurizers, antiseptics, anti-slip agents , Ingredients for smelting carburant, ingot protection slag, graphite bearing and other products.
In the casting industry, applying graphite to a solid surface can form a smooth film with strong adhesion, which is a good casting release agent.
- According to the national standard GB / T 3519-2008 of the People’s Republic of China, amorphous graphite is divided into two categories according to the requirements for the presence or absence of iron. Those with iron requirements are in the first category, indicated by “WT”, commonly known as “electric carbon”; those without iron are in the first category, indicated by “W”. The main products are graphite balls, graphite powder, graphite particles, graphite sand. amorphous graphite is divided into 8 grades of 65, 70, 75, 78, 80, 83, 85, 88 according to fixed carbon content, and common fineness is divided into 325 mesh, 200 mesh and 100 mesh
