Pyrolyticgraphite for product use is made by pyrolysis of propane or methane gas
in nitrogen atmosphere at high temperature and low pressure, and
directional deposition of carbon atoms on the die surface is directly
formed. The product has the characteristics of bright and clean, high
purity, compactness, strong acid resistance, strong alkali and so on. At
room temperature, strong acid and strong alkali have little corrosion
effect on the product. It is suitable for decomposing samples with
alkali or acid solvents, such as iron ore, manganese ore, silicate rock,
bauxite, stone coal, phosphate rock, non-ferrous metal
ore, cinder, coal ash, cement, glass and ceramics, and also for
dissolving and purifying precious metal products, fine chemical products
and reagents.
