  • Properties of fused silica

    Glass can be made from pure silica but quartz glass (also referred as quartz) has a high glass transition point at around 1200°C which makes it difficult to form into panes or bottles. Quartz glass is the purest form of SiO 2 and therefore the most valuable and sophisticated variety. Extremely clear glass can be used for optical fibers.
