Get PriceFused Silica is a result of melting synthetically derived silicon dioxide and is used in many of the same applications as fused quartz. The main differences are that fused silica transmits better in the UV and fused quartz is lower in OH content. Both are highly pure, have high chemical resistance, good thermal shock resistance, and low thermal expansion coefficient. SGP can CNC mill, cut ...
Get PriceGrinding; Milling; Hot forming. A lot of experience is necessary to do hot forming of fused silica. Due to the high melting point and its steep viscosity, the temperature range in which it can be processed is rather narrow. If the temperature is too low, fused silica is solid, if it is too high, it gets very soft, almost liquid and it evaporates to form soot dust. Additionally hot processing ...
