Amorphous Graphite is a form of elemental carbon crystallized predominantly in the hexagonal system. It is a high-energy crystalline carbon material, because of its unique structure and electrical conductivity, thermal conductivity, lubrication, temperature, chemical stability, which is widely used in metallurgy, machinery, environmental protection, chemicals, fire, new energy, nuclear energy , electronics, medicine, military and aerospace fields. Silicate mineral impurities varying in kind and percentage are usually associated with graphite in the ore. Foundry facings have accounted for nearly 20 percent of the total consumption in the past years. Low quality and amorphous graphite is suitable for this use. The graphite is mixed with a small amount of clay, suspended in an adhesive material and applied as thin coatings to mold surfaces to provide for clean and easy recovery of the metal castings.
Mesh size of amorphous graphite
Amorphous Graphite has numerous applications due its fundamental softness, including in lubricant formulations and as an additive to structural materials and metallic alloys. We provide natural amorphous graphite as a powder at -100 mesh, -200 mesh, and -325 mesh, as a grain with size ranges of 0-3mm, 0-6mm, 0-15mm, 1-5mm, 2-5mm, 1-6mm, and as briquettes with specifications of 45x38x25mm, 45x45x20mm, 30x25x20mm, 25x20x16mm, all available in the following purities: 70%, 75%, 78%, 80%, 83%, 85%, 88%, and 90%.
Standard of amorphous graphite
Natural Amorphous Graphite is generally immediately available in most volumes. We produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
