Glass Fused/
/

It is a form of silicon dioxide highly synthetic and pure. Fused Silica in crystalline form is not and has no color. It is a type of silica glass which has less thermal expansion and higher transmission power range of particularly ultraviolet spectra. Silica is the pure silica with only about of 99.4 to 99.9% of silica present in it. This is mostly fused silica used in industries dealing with electronics and are made by plasma arc, carbon electrode or gas fusion continuous extrusion and carbon arc. Because of its high insulation and dielectric properties, almost 70% of the electronics silica used in their experiments. Some of them also use a fused silica in the investment casting or as a refractory material, as if kept at high temperatures has the ability to recover their strength. Because of isolation and the dielectric properties, silicon is the most widely used in electronic circuits.

For many applications, silica comes with different grades. The most important application of fused silica which are high-energy use Laser Optics, where any other optical equipment is nothing compared with pure silica. Because of its purity and exceptional optical quality even if the laser high energy is transmitted does not affect the vast amount of material. In the production of prisms, windows and lenses of silica is used. Prisms which are mostly in the range from 0.16 to 3 vyoms are manufactured using fused silica. Depending on the transmission distance, the index of refraction may be around 1.55 to 1.40. It has a ability to maintain its strength even at high temperatures and because of this property is used as a refractory material well. This is mainly because they have high levels of silicon point fusion, resistance to abrasion is very high and low thermal expansion.

How fused silica is manufactured?

silica can be manufactured with the help of two basic steps:

1. Fused silica is produced by the synthesis process. Here the crystal is synthesized from products chemicals.

2. With the aid of electric or gas heating, the grains are fused silica fused silica produced. Depending on the applications, This mixture can be opaque or transparent.

Advantages:
Various advantages of using silica are:

1. High power resistance to thermal shock. Even if inserted into the red heat water directly, not crack.

2. Coefficient of thermal expansion is very low.

3. High power optical transmission spectra wider especially in the ultraviolet.

4. High resistance to chemicals.

5. Acting as large electrical insulation for electrical items and is therefore used in most electrical circuits.

6. Less constant value Permittivity and dielectric loss.

The applications that used fused silica are the windows, mirror substrates, pots, pans, pots, lenses, IR optical transmission, optical and UV transmission metrology components. Also used as a refractory material due to its high melting point and high abrasion resistance and low thermal expansion.
