Volcanic stone (volcanic rock or pumice) is a kind of glassy lava with dense pores formed by the rapid expansion of internal gas due to the sharp reduction of pressure after the sudden cooling of magma during the volcanic eruption. The pore volume accounts for more than 50% of the rock volume. It is called pumice because of its many pores, light weight and ability to float on the surface of the water. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire protection, acid and alkali resistance, corrosion resistance, and no pollution, no radioactivity.더 읽어보세요

Industrial alumina is prepared from bauxite (AlzOs-3H2O) and diaspore, and A1203, which requires high purity, is generally prepared by chemical methods. A1203 has a lot of homogenous crystals, there are more than 10 known, there are mainly 3 crystal types, namely A-Alzos, B-AlzOs, Y-AlzOs. Among them, different structures and properties are different, and it is almost completely converted into a-AlzO3 at high temperatures above 1300℃.더 읽어보세요
