expanded perlite formation

Perlite Wikipedia

Perlite is a non-renewable resource. The world reserves of perlite are estimated at 700 million tonnes.. The confirmed resources of perlite existing in Armenia amount to 150 million m 3, whereas the total amount of projected resources reaches up to 3 billion m 3. Considering specific density of 1.1 ton/m 3 confirmed reserves in Armenia amount to 136 mln. tons.

Corrosionpedia Expanded Perlite Insulation: Why

Expanded perlite is hydrophobic, and it has an inherent stone makeup that actively inhibits corrosion. The dual nature of perlite allows it to work to prevent CUI even after elevated temperatures (greater than 450°F or 232°C) have oxidized the organic ingredients that make the insulation hydrophobic.
