Materials : Quartz

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.

Selection of materials

Microcertec uses standard grades of quartz from well-known producers like GE or Heraeus. We machine both quartz standard quality as well as semiconductor and optical grade quartz.

Properties

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

Our typical applications

Quartz is mainly used as :

- electrical insulators
- thermal insulators
- structural parts
