Fused Quartz consists of high-purity Silica (SiO2) with a purity level of 99.998%

Fused Quartz also offers a number of unique properties that make it ideal in a variety of applications where other materials prove to be problematic. These discs provide extremely high purity, a high softening temperature (1670°C), optical transparency over a wide range, low thermal expansion, excellent thermal shock, and resistance to a large number of elements and compounds.

Ground and polished discs manufactured from this material are invaluable in research and industry applications.
