Specifications
Introduction: Graphite crucibles can be roughly divided into four categories. 1.Pure graphite crucible. The carbon content is generally greater than 99.9%, and it is made of pure artificial graphite material. It is only recommended to use other furnace types carefully for electric furnaces. 2.Clay graphite crucible. It is made of natural graphite powder mixed with clay and other binder oxidation-resistant materials, and is rotationally formed. It is suitable for factories with low labor cost and low operating rate. 3.Silicon carbide graphite crucible, rotationally formed. It is made of natural graphite powder, silicon carbide, aluminum oxide, etc. mixed as raw materials, spin-molded, and added with an anti-oxidation layer. The service life is about 3-8 times that of the clay graphite crucible. The bulk density is between 1.78-1.9. Suitable for high temperature test smelting, popular demand. 4.The silicon carbide graphite crucible is formed by isostatic pressing, and the crucible is pressed by an isostatic pressing machine. The service life is generally 2-4 times that of the rotary formed silicon carbide graphite crucible. It is the most suitable for aluminum and zinc oxide. Other metals should be carefully selected, and induction furnaces should be selected carefully. Due to the high cost of isostatic pressing, there is generally no small crucible.
