Corundum Mullite Crucibles
Product Description
Corundum Mullite Crucibles are made of corundum mullite with good thermal shock stability after high temperature sintering. Because of the refractory raw materials, they have good high temperature resistance and is suitable for high temperature applications, such as metal processing, glass melting, rapid thermal cycling, etc. Corundum Mullite Crucibles are widely used in laboratory and industrial analysis, as well as the melting of metallic and non-metallic material samples. We have provided a large number of alumina crucibles and boats for metallurgy, chemical industry and material science applications.
Product Advantages
1). High temperature resistance.
2). Strong thermal shock stability.
3). Resisting corrosion and stripping.
4). Long working life.
5). Corundum Mullite Crucibles can effectively reduce probability of product's deformation, slag stripping etc defects.
