Fused Silica Custom Shapes
from Accuratus Corporation

Fused silica is a noncrystalline (glass) form of silicon dioxide (quartz, sand). Typical of glasses, it lacks long range order in its atomic structure. It ’s highly cross linked three dimensional structure gives rise to it ’s high use temperature and low thermal expansion coefficient. [See More]
