Silicon carbide ceramic crucible is made of silicon carbide material and is a commonly used high-temperature container. Silicon carbide ceramic crucible has excellent high-temperature stability, excellent corrosion resistance and low thermal expansion coefficient, which enables it to withstand extreme thermal stress and chemical erosion in high-temperature environments. It is used for sample accommodation and processing in experiments or industrial processes such as melting, sintering, heat treatment and chemical reactions under high-temperature conditions.
Our silicon carbide crucible is fabricated by high purity isostatic pressing and 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 a certain strain resistance to acute heating and acute cooling. It has strong corrosion resistance to acid and alkali solution and excellent chemical stability. The specific model can be customized by drawing and sample, and the material is 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.
