Nontransparent fused silica glass is prepared from quartz sand with an impurity content of 0.1 wt.% (i.e., 1000 ppm), whose annual output is many thousand tons, whereas the annual output of transparent quartz glass amounts to only several hundreds of tons [1, 2, 4, 5, 37]. Finally, Silica glass, also known as fused quartz, consists of mostly pure silica (SiO2). Fused Silica Properties; Optical Glass & Technical Glass; Ceramic Properties; Applications. This material provides very high thermal shock resistance as well. Key Fused Silica Properties In contrast to the presence of other ingredients in common glasses for reducing the melting temperature, fused silica has no other ingredient. In our previous work, we reported the extrusion-based 3D printing of . The annual output of optical quality fused silica glass is some tens of . Production of Fused Silica or Quartz Glass There are two basic ways of making quartz / silica glass: By melting silica grains either by gas or electrical heating (the type of heating affects some optical properties). Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects. Popular Products of UV Fused Silica Grades A Glass Optics by Fused Silica Optics - Fused Silica Optics Co.,LTD from China. SiCl4) that are burned in the presence of oxygen to form silicon dioxide.

Quartz, Fused Quartz, Quartz Glass, Silica, Silica Glass, all these names are confusing and often not very well defined by their . For each property being compared, the top bar is borosilicate glass and the bottom bar is fused silica. Fused silica is an amorphous grade of silica known for its low thermal expansion and thermal shock resistance. The finished product is a transparent glass with an ultra-high purity and improved optical transmission. Fused silica is a common glass type used in the optics industry to manufacture optical components such as lenses, windows, mirrors, prisms, and beamsplitters. Extremely low coefficient of expansion, making it far more shock resistant than any other refractory material Best transmission characteristics of any standard glass: 220 nanometers to 3 microns for standard semiconductor-grade fused quartz, and 175 nanometers to 3 microns for many types of fused silica Fused quartz glass, also called fused-silica glass or vitreous-silica glass, is fabricated by purifying and melting down naturally occurring crystalline silica, found in sand or rock crystal, either with electrical or flame fusion.
