What is Perlite? – Ferba Group

Crushed raw perlite is used mainly as a slag perlite ore contains between 2% and 5% combined or occluded water. When rapidly heated above a temperature of 1000oC, the graded perlite ore particles melt and expand to between 4 and 40 times the original volume as the combined water vaporises and forms microscopic cells or tiny bubbles in the heat softened glass.
