Perlite - an overview | ScienceDirect Topics

Perlite is a volcanic material, mostly composed of aluminium silicate, obtained from Greek islands. Raw perlite is heated to about 750 °C (1,400 °F), which causes bursting of the particles yielding glassy structures. These are milled to a free flowing powder, which is about 30% lighter per unit volume than kieselguhr.
