Perlite Expansion Furnace are specially used to manufacture closed pearlites, hollow pearlite vitrification microsphere. 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.

Perlite is a unique volcanic mineral which expands from four to twenty times its original volume when it is heated. Perlite can reach temperatures of approximately 1600-1700 degrees F. The media's expansion is due to the presence of two to six percent combined water in the crude perlite rock, which causes the perlite to pop in a manner similar ...

Perlite is a naturally occurring volcanic rock formed from siliceous lava or ash. Due to rapid cooling, the lava or ash solidifies into a glass-like rock. Over tens of thousands of years, surface and ground water infiltrates the rock and becomes trapped in the glass structure. When heated at temperatures from 750 to 1,250°C, perlite expands ...
