Refractory mullite cordierite ceramic setter plate for stove furniture
corundum mullite ceramic
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.
Furniture Features:
1. Good thermal conductivity
2. Good high temperature strength
3. Wear resistant and erosion resistant
4. Good oxidation resistance
5. Not easy in deformation and cracking
6. Good thermal shock resistance
7. Good corrosion resistance
