Quartz, or fused silica, can be machined like any other ceramic material thanks to diamond tools. Thus Microcertec can realize customized parts made of quartz with various sizes and shapes, high level of precision but without any optical required performances or surface finish. The most important properties of the quartz is its low coefficient of thermal expansion. From an optical point of view, the quartz is generally transparent to the infra-red wavelenghts. Applications Quartz is mainly used for : electrical insulators thermal insulators structural parts Materials From a general point of view, quartz shows : good electrical insulation very small coefficient of thermal expansion good thermal insulation good thermal resistance transparence to the infra-reds vaccum resistance Download Precision machining of quartz (374.69 Ko)
