GE 124 Fused Quartz
Glass Type: Fused Quartz / Silica
Description
Fused quartz Is a result of melting crystalline silica in the form of stone, sand or rock. It is sometimes used in the same applications as fused silica. The main differences are that fused quartz has a much lower OH content and fused silica transmits better in the UV. Both are highly pure, have high chemical resistance, good thermal shock resistance, and low thermal expansion coefficient. SGP can CNC mill, cut, drill, lap, and polish GE124 into any dimension or surface finish.
