GE 124/214 Quartz | China Glass Quartz Parts Inc.

Glass Type: Fused Quartz

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. CGQPI can CNC mill, cut, drill, lap, and polish GE124 into any dimension or surface finish.
