Calcined Kaolin, also known as calcined clay or metakaolin, is a high-temperature processed form of kaolin clay that has been thermally treated to remove moisture and increase its reactivity and strength. It is highly valued across multiple industries for its enhanced properties, making it an essential ingredient in ceramics, paper, construction, paints, and plastics. Its versatility and effectiveness contribute to its widespread use in both industrial and consumer applications.
Calcined Kaolin, in pottery, plays a vital role as a key additive that enhances the strength, whiteness, and thermal stability of ceramic bodies. When incorporated into clay mixtures, it helps improve workability and reduces the risk of cracking during drying and firing due to its low shrinkage properties. Calcined kaolin also contributes to the smoothness and finish of glazes, promoting better adhesion and a more refined surface texture. Its high degree of whiteness makes it ideal for producing fine porcelain and stoneware, allowing for vibrant glazes and intricate designs. Overall, calcined kaolin is essential in achieving high-quality, durable, and aesthetically pleasing ceramic products.
Appearance:
-Fine, white powder
-Smooth texture with a slightly glassy appearance due to the calcination process
Other applications in different industries:
