Properties of fused silica
Synthetic fused silica from Heraeus contains total metallic contamination below 1ppm. For fused quartz the amount is approximately 20 ppm and consists primarily of Al2O3 with much smaller amounts of alkalis, Fe 2 O 3, TiO 2, MgO and ZrO 2. OH content In addition to metallic impurities, fused quartz and fused silica also contain water present as OH units. OH content influences …

Fused Silica: A Transparent Look at a Complex Material
Despite fused silica's deceptively simple formula, it can exhibit various characteristics based on the production processes and the raw materials employed, which makes it a very versatile optical material. In general terms, fused silica has a very broad optical transmission window, ranging from the UV to the near-infrared (NIR).

Fused Silica Wafers for Research & Production
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).

Fused Silica Material Properties
Synthetic Fused Silica, which is manufactured from an extremely pure precursor, offers the highest transparency in the UV of any glasses. On the infrared side, the source of intrinsic absorption is molecular vibration. The Si-O bond has a very strong absorption peak near 8.9 µm and at 4.5 µm (overtone frequency).

fused silica industrial scale production
Fumed silica (CAS number-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area.

Making of fused silica
Historically, the first method of producing fused quartz was by small-scale fusion of quartz crystals in a flame. Heraeus chemist Richard Küch first began fusing quartz rock crystal in a hydrogen/oxygen (H2/O2) flame more than 100 years ago. Heraeus has been producing quartz glass on an industrial scale with this process ever since.
