High Temperature Resistance Cordierite Mullite Kiln Shelves For Kiln Firing
Product Feature
● High Temperature Resistance: Cordierite mullite has a refractory temperature of up to 900 to 1280℃, suitable for a variety of high-temperature environments.
● Thermal Shock Stability: Combining the characteristics of cordierite and mullite, this material has excellent thermal shock resistance and can effectively resist the thermal stress caused by rapid temperature changes, thereby extending the service life 12.
● Lightweight and Energy-saving: The material is relatively light and absorbs less heat. It can be made into hollow or thin-walled kiln furniture, which helps save fuel and reduce the burden on equipment 1.
● Chemical Stability: The combination of cordierite and mullite provides good chemical inertness, which can prevent adverse reactions with fired products and ensure product quality.
● High Mechanical Strength: The mullite part gives the material high mechanical strength, making it perform well under heavy loads and suitable for various industrial applications.
● Wide Application: Cordierite mullite board is not only used in kiln furniture in the ceramic industry, but also in electronic packaging materials and solar thermal power generation materials, showing its versatility.
