    Silicon processing from quartz to crystalline silicon

    silicon dioxide is found as huge deposits of quartzite or quartz sand. Moreover, many rocks contain quartz crystals. Therefore, it can be concluded that the resources of silicon are virtually unlimited (although purity varies considerably). The main applications of silicon are as follows deoxidation and alloying of steel and cast iron, alloying of aluminium, raw material in the chemical industry, and
