Chamotte

Short Description:

Chamotte is a high-quality hard refractory clay produced in Zibo, Shandong Province, China. The standard Al2O3 content of chamotte ore is 38%, after calcination the Al2O3 content is about 44%, and Fe2O3<2%. The composition is stable, the texture is uniform, the structure is dense, and the section is shell-shaped and white. It is used to produce high-quality clay refractory materials. The technical term is the first-grade hard clay clinker, the main chemical components are AL2O3 and SiO2, accompanied by a small amount of Fe2O3 and trace amounts of Na2O and K2O. The main mineral is kaolin.

The chamotte we call generally refer to CALCINED CLAY. . The content of Al2O3 in the calcined chamotte is about 44%, and the content of Fe2O3 is not more than 2%. The composition is stable, the texture is uniform, the structure is dense, and the section is shell-shaped.

The common colors of chamotte after high temperature calcination are: pure white, light gray, light yellow brown, and a small amount of brown iron sheet.

Features

Chamotte are not easily dispersed in water and have low plasticity.

Chamotte have heat resistance and sinterability

After being calcined at high temperature, the scorched gem has the characteristics of stable volume, high strength and low water absorption.

Application

Chamotte are used in the production of advanced refractory materials, ceramics, aluminum silicate refractory fiber production and military industry.

It is widely used in metallurgy, casting, chemical, ceramics, electric power, machinery, petroleum and other industries.
