Fused Silica SiO2 Material Properties

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