Chamotte

Chamotte is a calcined form of clay that is used primarily in refractory materials for its heat resistance. It has a rough texture and is typically beige or white. The primary producers of chamotte include China, Germany, and the United States. Chamotte is widely used in the ceramics, steel, and glass industries due to its ability to withstand high temperatures and thermal shock.

Key chamotte-producing countries include:

• China – ~40% of global production
• Germany – ~15% of global production
• United States – ~10% of global production
• India – ~10% of global production
• Brazil – ~5% of global production

Chamotte is made by calcining clay at high temperatures to drive off volatile components, leaving behind a dense, thermally stable material. The clay is mined, crushed, and then fired in kilns to produce chamotte. Depending on its intended use, the chamotte is ground to different grain sizes, which affects its suitability for various refractory applications.

Chamotte is primarily used in the production of refractories (~60%), which are essential for lining furnaces and kilns in the steel and glass industries. It is also used in ceramics (~30%) to enhance the thermal shock resistance of products such as tiles and pottery. Chamotte is valued for its ability to maintain stability under extreme heat.
