Recrystallized Silicon Carbide (RSIC) Kiln Furniture
Recrystallized silicon carbide kiln furniture includes beam, batt, plate, roller, tube, sagger, nozzle, pillars, crucibles, etc.
Compared with silicon carbide kiln furniture, recrystallized silicon carbide kiln furniture has the following advantages:
- Higher refractoriness
- Longer service life
NO.2 Cordierit-mullite Kiln Furniture Products (1300°C)
Cordierit-Mullite Kiln Shelves
Cordierite-Mullite kiln furniture is a combination of cordierite, mullite and a glassy phase. It possesses excellent thermal shock resistance and is suitable for high temperature environments. It is the best refractory for use in kiln furniture and kin construction where operating temperatures are under 1300°C.
- High Temperature Strength;
- Stronger Resistance to Deformation;
- Excellent Thermal Shock Resistance;
- Good Thermal Conductivity;
- Can be Designed According to the Actual Requirement.
Advantages of Kerui Ceramic Kiln Furnitures
