Chamotte, also known as calcined clay or flint clay, is a refractory material is a natural clay minerals calcined at 1300°C to 1600°C. after calcining ,make its the structure changed , organic matter and water was moved , resulting in a stable, inert ceramic with excellent refractoriness, mechanical strength, and thermal shock resistance.
It is widely used in productions of refractory bricks, castables, and ceramic for kiln linings, furnaces in steel, cement, glass and high temperature industries.
Chamotte’s low thermal conductivity and high abrasion resistance also makes it suitable for insulation and erosion resistance applications.
we , as a professional manufactures of refractory fire brick , always choose the high and pure Chamotte raw material , to keep the stead quality control of fire brick. our Calcined Flint Clay is from Zibo , which is famous basis of Calcined Flint Clay in China ,
