  • Fused quartz - Revolvy

    Jan 13, 2016· Fused quartz or fused silica is glass consisting of silica in amorphous (non-crystalline) form.It differs from traditional glasses in containing no other ingredients, which are typically added to glass to lower the melt temperature. Fused silica, therefore, has high working and melting temperatures. The optical and thermal properties of fused quartz …

  • Fused Silica? Fused Quartz? What is the difference?

    Fused Silica (also known as Synthetic Fused Silica) is made from a silicon-rich chemical precursor, usually using a continuous flame hydrolysis process, which involves chemical gasification of silicon, oxidation of this gas to silicon dioxide, and thermal fusion of the resulting dust (although there are alternative processes).

  • BK7 Glass - Optical Glass - Glass Dynamics LLC

    BK7 is a high quality optical glass that is used whenever the additional benefits of fused silica are not required. Since BK7 performs well in all chemical tests, and no additional or special handling is required, costs of manufacturing are reduced.

  • Fused Silica | SiO2 Material Properties

    Fused Silica, SiO 2 Glass 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. It’s highly cross linked three dimensional structure gives rise to it’s high use temperature and low thermal expansion coefficient.
