Properties

Silica is the most abundant of all minerals. Silica in nature is called silica, which accounts for about 12% of the total weight of the earth's crust. There are three different crystal forms of silica: quartz, scaly quartz and cristobalite. Quartz is the most stable at room temperature and the other two are stable at high temperature. They also exist at room temperature because of their slow transformation into quartz.
