Summary of graphite materials ore resource，Graphite is one of the carbon crystal mineral, lubricity, chemical stability, high temperature resistant, the thermal conductivity of the conductive, special and plasticity, coating and other excellent properties, its application field is very wide.The graphite in the metallurgical industry is mainly used as refractory materials;Used for mould in the casting industry and antirust coating;In the electrical industry for the production of carbon electrode, electrode carbon rods, batteries, made of graphite can be used as a television tube coating, made of carbon products can be used for generators, motors, communications equipment and so on many aspects;In the mechanical industry used as aircraft, ships, trains, and other high-speed operation of the machinery lubricants;In the chemical industry used…
The graphite products are divided into two major categories of flake graphite and microcrystalline ink: flake graphite refers to the natural crystal graphite, the shape of covered, by crystal, flaky graphite ore processed, ore dressing, sometimes by purification products;Microcrystalline graphite has called earthy graphite or amorphous graphite, refers to the tiny natural graphite crystals composed of dense aggregate, by implicit crystal, earthy graphite ore processed, some after the separation, purification products. Flake graphite according to fixed carbon content is divided into high purity graphite, graphite in high carbon graphite, carbon and low carbon graphite four types, according to the product particle size, fixed carbon content is divided into 212 kinds of brands, various grades of graphite products technical requirements are…
Using graphite as electronic conductor material of the electrode.Graphite chemical properties is stable, low overpotential of chlorine, good mechanical strength, easy processing, price moderate.Is widely used in industry, such as used in dry cells positive electrode collector body (graphite rod), industrial electrolytic cell anode, etc.Of chlor-alkali industry in the early, chloride with graphite electrode material, but the drop of slag after chlorine corrosion such as chip jams diaphragm is easy to cause short circuit, shorten the life of electrolyzer, is gradually replaced by titanium form stable anode.In the lab is also commonly used as a price lower inert electrodes. The graphite used discharge loss smaller;Because the spark oil also contains C atoms, in electro discharge machining, the C atoms are…
