PRODUCT PARAMETERS
Description
Cordierite-Mullite Kiln Furniture
Cordierite-Mullite kiln furniture is a high-quality refractory kiln furniture product made primarily from high-quality cordierite and mullite through high-temperature sintering. The products are specifically designed for use in roller kilns, tunnel kilns, and box kilns to support the high-temperature firing of art ceramics, daily-use ceramics, sanitary ceramics, magnetic materials, and other products. The products possess excellent thermal shock resistance, high-temperature strength, and long service life, making them an ideal kiln furniture choice for various ceramic and magnetic material firing processes.
Product Features
- Excellent Thermal Shock Resistance
Cordierite has an extremely low coefficient of thermal expansion, giving the product excellent thermal shock resistance. It can withstand frequent temperature cycles without cracking or peeling, making it suitable for rapid firing processes in various kilns.
- High High-Temperature Strength
The mullite phase endows the product with excellent high-temperature mechanical strength, maintaining good load-bearing capacity at firing temperatures. It does not deform or bend during high-temperature firing, ensuring product flatness.
- Long Service Life
The material has a stable structure and excellent corrosion resistance. It is not easily worn or cracked with long-term use, resulting in a long service life and high overall cost-effectiveness.
- No Pollution to Ceramic Products
High-purity cordierite-mullite material has good chemical stability. It does not react with ceramic products at high temperatures, does not slag or shed powder, ensuring the surface cleanliness of the fired product.
- Low coefficient of thermal expansion
The cordierite phase imparts an extremely low coefficient of thermal expansion to the material, resulting in good dimensional stability. It maintains structural integrity during repeated temperature fluctuations, reducing damage caused by thermal stress.

Frequently Asked Questions (FAQ)
- What is the difference between cordierite-mullite kiln furniture and pure mullite kiln furniture?
Cordierite-mullite kiln furniture, containing the cordierite phase, has a lower coefficient of thermal expansion and superior resistance to thermal shock, making it particularly suitable for intermittent kilns with frequent temperature increases and decreases. Pure mullite kiln furniture has higher high-temperature strength and is suitable for higher temperature or heavier load-bearing conditions. The choice between the two can be made based on actual process conditions.
- What is the maximum operating temperature of this product?
The maximum operating temperature can reach 1350~1400℃, fully meeting the firing temperature requirements of art ceramics, daily-use ceramics, sanitary ceramics, and magnetic materials.
- How is the product’s thermal shock resistance?
Due to the extremely low coefficient of thermal expansion of cordierite, the product has excellent resistance to thermal shock and can withstand frequent temperature cycles without cracking, making it particularly suitable for rapid firing processes.
- Will the product contaminate ceramic products?
No. The product uses high-purity cordierite-mullite material, which does not slag, shed powder, or release volatile impurities at high temperatures, ensuring a clean surface on the fired product.
- Do you support customized sizes and shapes?
Yes. We can customize cordierite-mullite kiln furniture of different shapes and sizes according to the customer’s kiln internal dimensions and product specifications.
