Introduction To High Purity Graphite

Performance: The scales have complete crystallization, thin flakes and good toughness, excellent physical and chemical properties, and have good thermal conductivity, temperature resistance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance and other properties.
Description: High-purity graphite (also known as flaky high thermal conductivity carbon powder) has the advantages of high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, small resistivity, corrosion resistance, and easy precision machining. It is an ideal inorganic non-metallic materials. Used for processing and manufacturing electric heating elements, structural casting molds, crucible boats for smelting high-purity metals, heaters for single crystal furnaces, graphite for EDM, sintering molds, electron tube anodes, metal coating, graphite crucibles for semiconductor technology, Graphite anodes, grids, etc. for emitting electron tubes, thyratrons, 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 wear resistance, self-lubricating, easy processing, etc., and is widely used in metallurgy , chemical industry, aerospace, electronics, machinery, nuclear energy and other industrial fields. In particular, large-scale and high-quality high-purity graphite, as an alternative material, has broad application space and broad application prospects in high-tech and new technology fields.
Purification methods can be divided into two categories: one is wet purification, including flotation, acid-base method, hydrofluoric acid method; the other is fire purification, including chlorination roasting method and high temperature method.
