What are the technical parameters for hard calcium silicate stone slabs with a density of over 500? Hard silica calcium stone slab is a common insulation material. The main raw materials of hard silica calcium stone slab are calcium hydroxide and quartz sand, which are generated by high-temperature and high-pressure hydrothermal reaction. The size can be customized according to the needs of use, and it has the characteristics of high temperature resistance, good insulation, high strength, fire insulation, low thermal conductivity, and excellent thermal shock resistance. The finished hard silica calcium stone slab can withstand a high temperature of 1050 ℃.
