Natural pearlite increases the porosity at 50-80 and volume at 10-20 times after crushing and thermal processing. It is applied in various industries and an agriculture. Swollen pearlite is a good stuff for powder and vacuum-powder of thermal insulation at blocks of air separation, capacities for liquid cryo-agents (methane, oxygen, nitrogen, argon and others). The technology of its manufacture at new factory in Stary Oskol (Russia) is described. Various technological, physical and chemical properties of pearlite sand are analyzed in comparison with other manufacturers. Its high quality and low value of heat conductivity proves to be true that allows to use the swollen pearlite as effective thermal insulation.
