Product Description
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its light weight after processing.
It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. When perlite ore is rapidly heated to temperatures of around 900°C (1,700°F), trapped water molecules turn into steam in the rock and expand like popcorn. It is a commercial product widely use in Horticulture, Construction material, Industrial products, Filter aid, and fillers. It’s useful for its light weight after processing. Perlite are also used in foundries, cryogenic insulation, and in ceramics as a clay additive.
