We know that the main component of glass is silicon oxide and other oxides. The main component of polished tile surface is quartz and other clays. The main component of quartz is silicon dioxide. The hardness of quartz is very high. Nowadays, the grounds of high-speed rail stations and subway stations are mostly paved granite (granite), and 50%-60% of the granite is quartz. Due to the high traffic of high-speed rail and subway stations, the paving needs high hardness and strength materials. ground.
