Calcined Kaolin - Uses and Benefits

Calcined Kaolin - Uses and Benefits

Calcined kaolin is a form of clay with many important uses. It is used for many purposes, from paper coating to petrochemical catalysts. It has been used in ceramics for thousands of years and is still used widely in a variety of products. This article will briefly discuss the uses and benefits of calcined kaolin. It will also give you a basic idea of how the clay is produced.

Calcined kaolin is anhydrous aluminium silicate that is refined by a process called calcination. This process increases the whiteness and thixotropy of kaolin particles. The result is a whiter, more uniform product that has superior electrical and dispersive properties. Calcined kaolin is an excellent choice for many applications. It can be purchased in small amounts and full-bags. If you are in the market for a high-quality product, you can benefit from quantity discounts.

Besides thermal tests, kaolin is subject to extensive agglomeration and dryer testing. The Innovation Center has several test kilns for calcination. These test kilns are designed to conduct batch and continuous kaolin calcination tests. With this data, an engineer can design a commercial-scale kaolin calcination unit that meets your specific needs.

Calcined kaolin is a great addition to kiln wash recipes. It is also useful for reducing the shrinkage of matte glazes, preventing cracks from forming in the surface. This material is also a great substitute for titanium dioxide, and can be used for up to 30% less. It has excellent mechanical and abrasion properties. It also helps improve the stability of paint in stock.

Besides its anticorrosive properties, calcined kaolin is an excellent filler for plastics and rubber. It improves adhesion and rheology, and can control the speed of application. Its high melting point makes it a great candidate for use in ceramics. It is also used to make tableware, wall tiles, and sanitary ware. It is also valued in face creams because it helps absorb sebum. It also acts as a sunscreen.

Compared to hydrous kaolin, calcined kaolin is more stable. The high concentration of alumina and silica is achieved by the calcining process. Since the process eliminates water from the clay, the resultant material is much lighter and less plastic than wet clay. So, if you're interested in using kaolin in your production, it's best to calcine it.
