Vermiculite

Production introduction

Vermiculite is a mineraloid of hydrated laminar magnesium-aluminum- iron silicate. Its chemical composition greatly varies and chemical formation could be simplified as(Mg,Fe,Al)3(Al,Si)4O10(OH)2·4H2O. When heated to a temperature of about 850-950℃, it instantly expands(exfoliates) up to 15-25 times as water flashing into steam, maximum 30 times its original bulk volume. There is a color change during expansion from golden brown into silver white depending upon the composition of the vermiculite and temperature. With such prominent characteristics as being fireproof, heat insulating, sound and moisture absorbing, non-toxic, lightweight and disease free, it is widely used in construction, chemical industry, petroleum, electronics, light industry, environmental protection and as a medium of agricultural chemical products etc.
