Through this process, silica becomes a sealant, an adhesive, or a lubricant. For it to become adequate to process food, Silica (SiO2) is reduced to silicon metal by coke in an arc furnace, to produce the Si precursor of the other chemical processes. The chemical process and production is dependent on the use of industrial sand.
High grade energy is needed to transform silicon oxide into pure silicon, to be hydrated producing the silanes. One possibile way to go about this is to use photovoltaic electricity to disassociate hydrogen and oxygen from water. Those gases could then be used to process sand into pure silicon and to obtain silanes.
Silicon is the second most abundant element in the earth’s crust, second only to oxygen. It is naturally found as fairly pure silicon dioxide and as silicates. The silicon dioxide is found as huge deposits of quartzite or quartz sand. Moreover, many rocks contain
polycrystalline silicon. During last years, growth of world production of PVCs was bigger than production of scrap, therefore world reserves of scrap is almost depleted and it is necessary to create new way for production of solar grade SGPF. Forecast for demand and delivery of polycrystalline silicon on world market is presented at fig.1 .
