Fused silica glass.

Glass codes 7980 7979 and 8655 are high purity non crystalline silica glasses with excellent optical qualities. Because of the way fused silica is made it has superior ultraviolet performance to natural quartz and is ideal for applications such as uv transmitting optics. We supply industrial fused silica a commercial grade of fused silica used in many sight glass applications as well as uv fused silica which can be selected for a low content of inclusions and or a high refractive index homogeneity if required. However fused silica exhibits superior optical and thermal properties which are distinct from fused quartz and other types of glass due to its very high level of purity 99 9999.

Fused silica is an entirely synthetic material and is technically the purest glass. Quartz is the most stable crystal modification at normal temperature and pressure conditions. Although the terms fused quartz and fused silica are used interchangeably the optical and. Fused silica therefore has high working and melting temperatures.

Silicon dioxide glass quartz fused silica silicon dioxide sio 2 is the most simple chemical composition of glass. It will devitrify above about 1100 c in the presence of contaminants such as sodium phosphorus and vanadium with the. Fused silica s cross linked 3d structure delivers exceptional thermal shock resistance uv transparency and near zero thermal expansion. Manufactured substances in industry glass nurain insyirah 402 mrsm gerik.

This is because of its manufacture from one single ingredient. The material is also chemically inert up to moderate temperatures except to hydrofluoric acid which dissolves silica. It has the highest temperature characteristics of any glass and it often begins as pure silicon gas. Fused silica is offered in many different grades to support various product applications.
