Quartz (SiO2 or silica) is useful in electronics for its piezoelectric and dielectric properties and has many and varied photonic applications. As a substrate it is very hard and comes in a number of different crystal orientations. This can present problems for diamond dicing and machining if the cutting parameters aren't carefully selected initially and monitored during the course of cutting. Kadco Ceramics has expertise in processing both natural and fused silica for applications as varied as crystal oscillators for clocks and lenses for spectrometers.
