Graphite crucible is mainly used to smelt copper, brass, gold, silver, zinc and lead, and other non-ferrous metals and their alloys.
Our graphite crucible are processed with high purity isostatic pressed graphite, which has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to acute heat and acute cooling. It has strong corrosion resistance to acid and alkaline solution and excellent chemical stability. The specific models can be customized with drawings and samples, and the materials are domestic graphite and imported graphite to meet the different needs of customers.
The main raw materials of graphite crucible are graphite, silicon carbide, silica, refractory clay, pitch, and tar, etc.
