Langfang Jin large crucible plant to introduce a lot of knowledge about the crucible, want to know more you can log: www.jindagg.com. Graphite crucible is generally used for actual production, mainly for the smelting of copper, aluminum, gold, silver, lead, tin, zinc and other nonferrous metals and alloys can also be used for glass and steel alloy melting substances; addition, some purity high graphite crucible used in the production of semiconductor materials such as silicon, polysilicon, refractory metal and alloy sintered, high temperature vapor deposition. The main raw material of the graphite crucible, the crystalline natural graphite. Therefore, it is natural and right to maintain a variety of physical and chemical properties of the original ink. Namely: has good thermal conductivity and high temperature resistance, high temperature use, the thermal expansion coefficient, for emergency heat, quench with certain anti-strain properties. Acid, alkaline solution of a strong corrosion resistance, excellent chemical stability. http://www.jindagg.com/products_view.asp?id=1067
