Performance: Scale crystals are complete, thin and tough, good physical and chemical properties, good thermal conductivity, temperature resistance, self-lubricity, conductivity, thermal shock resistance, corrosion resistance and other properties.

Description: High-purity graphite (also known as scaly high thermal conductivity carbon powder) has the advantages of high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, small electrical resistivity, corrosion resistance, and easy precision machining. It is an ideal inorganic material. Non-metallic materials. Used for processing electric heating elements, structural casting molds, crucible boats for smelting high-purity metals, heaters for single crystal furnaces, EDM graphite, sintering molds, tube anodes, metal coatings, graphite crucibles for semiconductor technology, Graphite anodes, grids, etc. for emission tubes, thyristors and mercury arc rectifiers.

Features and applications: High-purity graphite has the characteristics of high strength, high density, high purity, high chemical stability, dense and uniform structure, high temperature resistance, high electrical conductivity, good abrasion resistance, self-lubrication, and easy processing.It is widely used in metallurgy. , Chemical industry, aerospace, electronics, machinery, nuclear energy and other industrial fields. In particular, large-scale, high-quality, high-purity graphite, as an alternative material, has a wide application space in the high-tech and new technology fields and has a broad application prospect.
