Expanded clay has the form of oval or round granules. This material is obtained by firing in furnaces with constant rotation of clay rocks, which tend to swell with a sharp increase in temperature to 1300 ° C. Expanded clay grain looks like a vitreous porous mass, coated. Depending on the clay processing mode, expanded clay of various bulk density and sizes can be obtained, which determines the quality of expanded clay.
