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, low resistivity, corrosion resistance, easy precision machining, etc. It is an ideal inorganic 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, electron tube anodes, metal coating, graphite crucibles for semiconductor technology, Graphite anodes, grids, etc. for emission 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. It is used in metallurgy, Chemical, aerospace, electronics, machinery, nuclear energy and other industrial fields. Large-scale, high-quality high-purity graphite, as an alternative material, has broad application space and promising application prospects in the field of high-tech and new technologies.

The purification methods can be divided into two categories: one is wet purification, including flotation method, acid-base method, and hydrofluoric acid method; the other is fire purification, including chlorination roasting method and high temperature method.

Key words: high purity graphite, large size and fine structure

What are the processing methods of graphite

The requirements of modern graphite processing industry for graphite products have developed in two aspects: one is to require large crystal flakes to achieve high purity, and the other is to require ultra-fine graphite product particles (such as less than 1 μm or 0.5 μm). China has established graphite purification and fine powder processing production lines in Nanshu, Beishu, Liumao, Xinghe and other graphite processing plants. The purification method is mainly chemical purification. The mature process of graphite chemical purification is to use caustic alkali and graphite to melt at 700 ℃, wash to neutrality, and then add hydrochloric acid treatment and washing, so that the carbon content of graphite reaches 98%-99%. There are also manufacturers who use hydrofluoric acid treatment to produce high-purity graphite.
