High Purity Graphite Crucible

Graphite Crucible

 

1.Introduction

The material of graphite crucible  can be divided into artificial graphite,clay bonded graphite, and carbon bonded graphite.Artificial graphite crucible is made of graphite electrode as material and made out.

Clay bonded graphite, the main ingredient is natural crystal graphite and clay Now only used in small amount of high-temperature melting of cast iron, cast steel melting and melting of precious metals.

Carbon bonded graphite, the main ingredient is natural crystal graphite and silicon carbide. Mainly used in  the melting of  the majority of non-ferrous metals such as copper alloy and aluminum alloy
