  • Quartz Properties

     · Mechanical properties of fused quartz are much the same as those of other glasses. The material is extremely strong in compression with design compressive strength of better than 1.1 x 10 9 Pa (160 000 psi). Surface flaws can drastically reduce the inherent strength of any glass so tensile properties are greatly influenced by these defects.

     · Manufactured glass is a material formed when a mixture of sand soda and lime is heated to a high temperature and stays in a molten liquid state. 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.
