The pan based Graphite felt was treated by a special process high temperature graphitization, with light weight,high carbon content,ablation resistance,corrosion resistance,high purity,high temperature without volatile,small coefficient ofthermal conductivity,without any deformation. The graphite felt is normally classified into asphaltic based graphite felt, PAN based graphite felt &rayon-based graphite felt. The mainly application of the graphite felt is electric conduction in the photovoltaic industry, as the heat retaining material, thermal insulation material for the smelting furnace and vacuum furnace, and in chemical industry it could be the filtration material. it is used to vacuum furnace(especially suitable for the single crystal furnace) as insulation heat preservation material,also can be used as infrared heating wire and electrode materials. The graphite felt is formed after…
The Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.Graphite crucible, which is divided into general type of graphite crucible, special type of graphite crucible, high purity graphite crucible.The main raw materials of Graphite crucible is natural crystalline graphite. Therefore, it maintains the original natural graphite various physical and chemical properties. Graphite crucible has good thermal conductivity and high temperature resistance;Uder the high temperature, the thermal expansion coefficient is small, rapid heating, quench with certain anti-strain properties. The strong corrosion resistance of acid, alkaline solution has excellent chemical stability. Graphite crucible, with their more excellent performance, in metallurgy, casting,mechanical, chemical and other industrial sectors, is widely used in smelting…
There are many kinds of graphite products, such as ordinary graphite, impregnated graphite, fine graphite, high purity graphite, isostatic graphite, and a very special kind of graphite, that is, electric spark, graphite, or EDM graphite! EDM graphite is mainly used in the production of dies. It has excellent properties that copper metal can not match. The electric spark graphite itself has the characteristics of non-metallic material, and it also has some characteristics of metal. Electric spark graphite density is smaller than copper, light quality, can bring many benefits to production; easy processing; from hardness, electric spark graphite is 1/3 of copper metal; and conductivity is less than metal copper; The high temperature resistance of electric spark graphite is better than…
