Cordierite-Mullite Kiln Shelves/Furniture is highly favored in the ceramic industry due to its exceptional thermal stability, low thermal expansion, and high thermal shock resistance. This type of kiln furniture is primarily used to support ceramic products during firing, ensuring even heat distribution and reducing the risk of cracking or deformation. Its durable and lightweight nature allows for repeated use in high-temperature applications, thereby enhancing the efficiency and performance of the ceramic manufacturing process.
