# Discover the Benefits of Calcined Kaolin in Industry.
Calcined kaolin is a versatile and essential material widely used across various industries. The process of calcination involves heating kaolin clay to high temperatures, transforming it into a white, fine powder. This post will uncover the numerous benefits that calcined kaolin brings to different sectors, focusing on its applications and advantages.
## What is Calcined Kaolin?
Calcined kaolin, also known as metakaolin, is produced by the thermal treatment of natural kaolin clay. The calcination process removes water content and modifies the structural properties of the clay, enhancing its performance in industrial applications. Its fine particle size and high brightness make it highly sought after, particularly in the following industries:
- **Paper and Packaging**.
- **Paints and Coatings**.
- **Ceramics**.
- **Plastics**.
- **Rubber**.
## Advantages of Calcined Kaolin.
Calcined kaolin offers an array of unique qualities that provide significant benefits across various applications:
### 1. Improved Rheological Properties.
One of the standout features of calcined kaolin is its enhanced rheological properties. This attribute makes it an excellent additive in formulations where viscosity control is crucial, such as in paints and coatings.
### 2. Whiteness and Opacity.
The high whiteness and opacity of calcined kaolin greatly improve the aesthetic quality of products. In the paper industry, for instance, using calcined kaolin allows manufacturers to create brighter sheets, enhancing print quality.
