Chamotte is a refractory material made from calcined and crushed clay. It's essentially a byproduct of the refractory brick manufacturing process. The clay used in chamotte production typically has fewer impurities than the clay used for other ceramic products. Chamotte is a versatile and essential raw material widely used in various industries, particularly in ceramics and refractories.
Its unique properties make it valuable for applications requiring high thermal resistance and mechanical strength.
