High Temperature Sialon crucibles up to 1,800 degrees Celsius (in a controlled atmosphere), and have good resistance to chemical erosions and thermal shock. 

Sialon crucibles are an excellent alternative to graphite crucibles for the melting of aluminum, copper and other metals. They have good resistance to chemical erosions and thermal shock. Especially Sialon crucibles are an excellent alternative to graphite crucibles for the melting of aluminum, copper and other metals. Silicon Nitride crucibles have the advantages of high purity, high temperature resistance, with big size, good thermal insulation, economization on energy ,quality stability etc.

Sialon crucibles are widely used in many manufacture processes including precious metals, vaporizing of molten aluminium.

Sialon ceramics is one of the few materials that can combine the high purity and high temperature properties required for these processes.
