Important Applications of Calcined Kaolin

Calcined kaolin has a wide range of important applications in the ceramics industry. It is used in paper coating and as a petrochemical catalyst. In addition, it has many useful refractory properties. This makes it an interesting material to use. This article outlines a few of the important applications of calcined kaolin.

One of the key benefits of calcined kaolin is its variability. While it exhibits a great deal of variability when used in raw form, its versatility is enhanced by calcination. Calcination requires expert knowledge of kaolin material properties. However, calcination is a relatively well-established thermal process. This means that it requires careful monitoring and testing to produce exact results.

One method of creating calcined kaolin is to bisque fire raw kaolin. This process requires the use of a small bisque vessel and a slow ramp. The resulting kaolin is a white, non-plastic powder. Though calcination destroys some of the plasticity of the kaolin, it keeps its chemistry to retain its fired properties.

Calcined kaolin has a wide range of applications in the ceramics industry. Many potters use it in their slip glazes for leather-hard ware. This type of glaze is intentionally high in clay content, and calcined kaolin is frequently used as a clay fraction in greenware slip glazes. It reduces cracking caused by shrinkage.

Calcined kaolin is also used in engineering thermoplastics. Its calcining process removes the water molecules from the kaolin. This means that the kaolin will no longer keep paint solids suspended. It is also a cost-effective antiblock additive.

Calcined kaolin is an important industrial mineral, and has numerous applications. It is an important ingredient in paints, refractories, technical ceramics, and other products. Its refractory properties make it a valuable commodity for many industries, and calcined kaolin is seeing increasing demand.

Calcined kaolin is anhydrous aluminium silicate. The calcination process increases the whiteness of the kaolin particles, improves their electrical properties, and alters their size. These properties make calcined kaolin an excellent substitute for Titanium Dioxide and other extender pigments.
