Cordierite ceramic plates are made of cordierite ceramic. Cordierite ceramic is a type of magnesium aluminum silicate with particularly good thermal shock properties. Cordierite also has low thermal conductivity and thermal expansion, while also being cost-effective. Often used as a structural ceramic for kiln furniture applications, it also finds uses in other applications where rapid temperature changes take place.

1. Kiln Furniture: Cordierite ceramic plates are extensively used as kiln shelves, setters, and tiles in the ceramics industry. Their ability to withstand high temperatures and thermal cycling without warping makes them ideal for supporting ceramic wares during firing processes in kilns.
2. Pizza Stones and Baking Stones: In the culinary world, cordierite ceramic plates are commonly used as pizza stones and baking stones. Their excellent heat retention and even heat distribution make them perfect for baking pizzas, bread, and other baked goods, providing a crispy crust and evenly cooked products.
3. Infrared Heater Components: Cordierite plates are used in infrared heaters as emitter plates. They effectively radiate heat when heated, making them suitable for industrial heating applications such as curing, drying, and space heating.
4. Heat Shields: Due to their high-temperature stability and low thermal conductivity, cordierite ceramic plates are used as heat shields in various industrial applications. They help protect sensitive components from direct heat exposure in furnaces, ovens, and other high-temperature environments.
5. Support Plates in Industrial Processes: In industrial processes, cordierite plates serve as support plates for components that need to be heated or cooled rapidly. Their thermal shock resistance ensures they can handle rapid temperature changes without cracking.
6. Insulation Plates: Cordierite ceramic plates are used as insulation plates in high-temperature applications. Their low thermal conductivity makes them effective barriers against heat transfer, protecting equipment and structures from excessive heat.
7. Microwave Kiln Shelves: Cordierite plates are used as shelves in microwave kilns, which are small kilns designed for firing ceramics or glass fusing in a microwave oven. The plates provide a stable and heat-resistant surface for the materials being fired.
8. Barbecue Grills and Smoker Plates: Cordierite ceramic plates are sometimes used in barbecue grills and smokers as heat diffusers or deflector plates. They help distribute heat evenly across the grill surface, reducing hot spots and improving cooking results.
9. Laboratory Hot Plates: In laboratory settings, cordierite plates are used as hot plates due to their ability to withstand high temperatures and resist thermal shock. They provide a stable surface for heating samples and conducting experiments that require precise temperature control.
10. Industrial Pallets and Trays: Cordierite ceramic plates are used as pallets and trays in industrial furnaces and kilns for transporting and supporting products during high-temperature processing. Their durability and resistance to deformation make them reliable for repeated use.
Our Cordierite Ceramic Plate is carefully handled during storage and transportation to preserve the quality of our product in its original condition.
