Introduction of Corundum mullite crucibles with high temperature resistance :
Mullite is a rare silicate mineral of post-clay genesis, It is produced during various melting and firing processes. Corundum mullite crucibles with high temperature resistance has the characteristics of compact structure, high compressive strength, good thermal shock stability, acid and alkali corrosion resistance, anti stripping, anti pulverization and long service life. The products are widely used in the smelting of rare earth magnetic materials, alloy materials and sintering of ceramic powders.
