    2021-5-11 · “Perlite is a generic term for a naturally occurring siliceous volcanic rock, grey to black in color. The crude perlite rock contains 2 to 6% combined water. During processing, the rock is rapidly heated to about 900 degrees Celsius causing the water to vaporize and creating countless tiny bubbles in the heat-softened glassy particles.

    Domestic production and prices of crude processed perlite in the United States were estimated to have increased in 2012 compared with 2011. Perlite trade, both imports and exports, slowed in 2012 compared with 2011. With imports of perlite down by about 13 percent and domestic production up slightly, the balance resulted in a consumption decrease of about 20 kt (22,000 st).

When heated to a suitable point in its softening range, it expands from four to twenty times its original volume. This expansion is due to the presence of two to six percent combined water in the crude perlite rock.
