Macro Photo Of Ceramic Sand. Ceramite is also called ceramic sand, is a kind of ceramic particle product with high fracturing intensity, belonging to lightweight aggregate family. Ceramite has excellent properties, such as low density, high cylinder pressure,high porosity, tall softening coefficient , good frost resistance. So ceramite is widely used in building materials , gardening , refractory insulation materials, chemical, oil, and other departments. Made from bauxite, it is heat resistant, cheaper to produce and use, environmentally friendly.
