Abstract: 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 relatively simple, cheap and environmentally friendly processing due to the high quality huge reserve of quartz ores of hydrothermal geological origin. The possibility of using highly transparent first grade quartz lascas in conventional fusion processes allows the fabrication of nearly bubble free silica glass. Due to the increasing demand of silica glass for processing solar cells and other products, this material is certainly a strategic supply for the present and future scenarios.
