Cordierite-Mullite Kiln Furniture
Cordierite-Mullite Kiln Furniture
Characteristic of Cordierite-Mullite kiln furniture
Cordierite-Mullite kiln furniture is a combination of Cordierite, Mullite and a glass phase. It possesses excellent shock resistance and is suitable for load bearing at high temperatures and is the best refractory for use in kiln furniture and kiln construction where operating temperatures are under 1320℃. It is widely used in the tableware, sanitary ware, construction ceramics and technical ceramics fields.
Typical products for this application include:
Plain batts, hole batts, special-shape batts
