Expanded Perlite

Perlite is an amorphous volcanic glass that has a relatively high water content. It occurs naturally and has the unusual property of greatly expanding when heated sufficently.

Properties and uses

When it reaches temperatures of 850–900 °C, perlite softens (since it is a glass) and water trapped in the structure escapes and this causes the expansion of the material to 7–15 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles.
Unexpanded ("raw") perlite bulk density: around 1100 kg/m³ (1.1 g/cm³).
Typical expanded perlite bulk density: 30–150 kg/m³

Due to its low density and relatively low price, many commercial applications for perlite have developed. In the construction and manufacturing it is use in lightweight plasters and mortars, insulation, ceiling tiles and filter aids. In horticulture it makes composts more open to air, while still having good water-retention properties; it makes a good medium for hydroponics. Perlite is also used in foundries and cryogenic insulations.
