Types of Cordierite Kiln Furnitures









Introduction of Kerui Cordierite Kiln Furniture
Cordierite kiln furniture is made from a unique combination of cordierite and mullite, offering the best of both materials:
- Cordierite: Low thermal expansion (1.5×10⁻⁶/°C from 25~1000°C) and excellent thermal shock resistance.
- Mullite: High mechanical strength, high melting point, and chemical stability.
By combining these materials, we create kiln shelves products that are both durable and resistant to thermal stress. These features make them ideal for high-temperature applications.

Key Features of Cordierite Kiln Furniture
- Low Thermal Expansion
Cordierite’s low thermal expansion coefficient minimizes stress during temperature changes, reducing the risk of cracking. - Excellent Thermal Shock Resistance
The combination of cordierite and mullite creates microcracks at the interface, absorbing thermal stress and enhancing durability. - Lightweight Design
Hollow and perforated plates reduce weight, saving energy and improving heating efficiency. - High Mechanical Strength
Mullite’s high strength ensures the cordierite kiln shelves can withstand heavy loads and repeated use. - Long Service Life
Our products are designed for extended use, reducing replacement costs and downtime.


Applications of Cordierite Kiln Furniture
Cordierite kiln furniture is widely used in:
- Ceramic Industry: Firing tiles, tableware, and sanitaryware.
- Electronics: Manufacturing electrical ceramics and insulators.
- Glass Industry: Supporting glass products during annealing.
- Metallurgy: Heat treatment of metal components.
