通过热处理火山玻璃获得的膨胀珍珠岩是一种最有前途的建筑材料。膨胀珍珠岩的容重与原料的质量、预热条件和膨胀工艺过程有关,膨胀系数可在40～500公斤/米~3变动,圆柱体的抗压强度为5～40公斤/厘米~2。膨胀珍珠岩是高质量的隔热材料,具有良好的吸附特性和抗冻、抗水性能。这些就可预料有可能在建筑业中广泛的 Expanded perlite obtained by heat treating volcanic glass is one of the most promising building materials. The bulk density of expanded perlite is related to the quality of raw materials, preheating conditions, and the expansion process. The expansion coefficient can be varied from 40 to 500 kg/m3, and the compressive strength of the cylinder is 5 to 40 kg/cm2. Expanded perlite is a high-quality insulation material with good adsorption characteristics and antifreeze and water resistance. These are expected to be possible in the construction industry
