Strategic high quality quartz supply for fusion into silica glass

摘要

An extensive i n loc o survey o f main quartz producing regions in an extensive in loco survey of main quartz producing regions in Brazil integrated with physicochemical characterization studies of quartz lascas and their fusion into silica glass bring the possibility of obtaining high quality quartz powder supplies for various industrial applications. The advantage is the realtively simple, cheap and environmentally friendly processing due the high quality huge reserve of quartz ores of hydrothermal geological origin. The possibility of nusing highly transparent first grade quartz lascas in conventional fusion processes allows the fabrication of nearly hubble free silica glass. Due to the increasing demand of silica glass for processing solar cells and other products, this material is certainly supply for the present and future scenarios.
