Fused silica is high purity quartz sand that has been melted to form glass. High volume stability, low volumetric expansion and high purity make fused silica a very useful and versatile material for refractory appliions, whether in aluminum launders or other highly cyclical appliions. Our fused silica, TecoSil® has an extremely low thermal expansion coefficient, consistent chemistry ...
Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semimetallic or metalloid, because it has several of ...

· Silica dust, paints, coatings and more can be extremely hazardous to operators. For construction jobs using power tools, a common way to collect silica dust is by using a vacuum connected power tool. This system allows the silica dust to be collected at the source while the operator performs the task, offering additional protection to the operator. Users can also suppress silica dust with a ...
The silica sand used in abrasive blasting typically fractures into fine particles and becomes airborne (see Figure 1). Inhalation of such silica appears to produce a more severe lung reaction than silica that is not freshly fractured [Vallyathan et al. 1988]. This factor may contribute to the development of acute and accelerated forms of silicosis among sandblasters. Figure 1. Sandblaster ...

Silicarelated diseases are associated only with crystallinefree silica. The most common examples of crystallinefree silica are beach or bank sands. A third form of free silica is fused silica which is produced by heating either the amorphous or crystalline forms. Other forms include cristobalite and tridymite. Workers exposed to silica dust are often exposed to asbestos as well and many ...
Silica sand for sandblasting. Sandblasting wood to create art or signs typically requires a portable pressure blaster with a hose to a handheld nozzle used to accurately direct the flow of highpressure abrasive on the portions of the object to be removed. Portable sandblasting equipment generally consists of an air compressor, a reservoir for abrasive material, a propulsion system, and a ...
silica under the influence of heat in the presence of a flux forms silies with sodium or potassium, and calcium, lead, etc., and the alkaline silie then dissolves 'the remaining silies. It is this solution that solidifies into glass on cooling. Glass may be divided into four general classes plate, window, green bottle, and flint. Owing to manufacturing conditions, few makers follow ...
