From raw material selection, semi-finished product manufacture, precision machining, impregnation, purification, and coating. This is how we ensure the consistent high quality and performance of our products.
B: Amorphous graphite
Amorphous graphite, earthy graphite, is also microcrystalline graphite and black lead powder. Amorphous graphite does not really have no graphite crystals like his name, but its crystals are too small and have a microcrystalline structure. X-ray analysis shows that amorphous earth-like graphite contains 15% to 45% of crystalline graphite, so amorphous graphite is also called microcrystalline graphite.
Amorphous earthy graphite can be divided into two types according to its output form: dispersed earthy graphite ore and dense massive earthy graphite ore:
1. Dispersed earthy graphite ore is mainly present in the fracture zone or cleavage fracture surface of flake graphite ore, with a mylonitic structure. The composition is complex and unstable, mainly composed of plagioclase, quartz, graphite, tremolite, chlorite, etc. The scales were squeezed and shattered into small fragments, some of them were black star-like dots, and their crystal shapes were difficult to identify with the naked eye. The grade of ore is low, generally 2%~3%, which has no industrial value.
2. The dense massive earthy graphite ore is mostly formed by contact metamorphism caused by thermal metamorphism in coal fields. The ore is dense and black, with a series of characteristics ranging from graphite to anthracite. Graphite content varies, generally 60% to 80%, the minimum is 15%, and the maximum is more than 90%. In addition to graphite, the constituent minerals include sericite, quartz, pyrite, calcite, limonite, clay, etc. This is the main characteristic of earthy graphite.
C: Application
Earthy graphite is widely used in foundry coatings, oilfield drilling, battery carbon rods, steel, casting materials, refractory materials, dyes, fuels, electrode pastes, as well as pencils, welding rods, batteries, graphite emulsions, desulfurizers, antislip agents Ingredients for smelting recarburizers, ingot injection mold slag, graphite bearings and other products.
