Fengcheng Ruixing Carbon Products Co., Ltd
High Purity Graphite refers to Graphite Carbon content > 99.99%, widely used in high-grade refractory material and coating of metallurgy industry, military industry, fire engineering pencil lead on material stabilizer, light industry, electrical industry of carbon brush, electrode of battery industry, fertilizer industry catalyst, additive, etc.
Performance: the scales of crystallization is complete, thin and toughness, good physical and chemical performance, good thermal conductivity, temperature tolerance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance and other properties.
Description: high purity Graphite (aka: scaly high thermal conductivity carbon powder) has high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, resistance coefficient, corrosion resistance, and the advantages of easy to precision machining, is the ideal inorganic non-metallic materials. Used for processing and production of electrical heating components and smelting casting mould structure, high purity metal with boat, single crystal furnace crucible with heater, edm graphite anode, metal plating, sintering mold, tube, semiconductor technology with graphite crucible, launch tube, thyratron and mercury rectifier with graphite anode, grid, etc.
Characteristics and applications: high purity graphite with high strength, high density, high purity, high chemical stability, uniform and compact structure, high temperature resistant, high conductivity, good wear resistance, self-lubrication, easy processing characteristics, widely used in metallurgical, chemical, aerospace, electronics, machinery, nuclear power and other industrial fields. Especially high quality high purity graphite, as an alternative material, has wide application space in high technology and new technology field and has wide application prospect.
The purification methods are divided into two categories: first, wet purification, including flotation, acid and alkali, and hydrofluoric acid. The second is fire purification, including chlorination roasting and high temperature method.
High purity graphite
Is widely used in high-grade refractory material and coating of metallurgy industry, military industry, fire engineering pencil lead on material stabilizer, light industry, electrical industry of carbon brush, electrode of battery industry, fertilizer industry catalyst, additive, etc. High purity graphite through deep processing, but also produce graphite, graphite sealing material and composite material, graphite products, graphite antifriction additives such as high-tech products, become the important nonmetallic mineral raw materials of various industrial sectors.
