The only argument against crystalline Si as the ideal PV material both now and in the future pertains to the fourth criterion. That is, the availability, collection, and manufacture of crystalline Si are extremely problematic. More precisely, because Si in nature is found only as impure, oxidized sand (silica/SiO 2) or silicates (a salt with SiO 4–x (4–2x)–), the …Web

What is Industrial Sand? Industrial sand is high-purity silica sand with uniform grain size and clean, well-rounded grains. It is made up of two main elements: silica and oxygen. To be considered a 'silica' or 'industrial' sand and be suited to industrial and manufacturing applications, the sand must contain at least 95% silica and oxygen.Web
