Steatite is an alternative to ceramics. This material consists to about 90 % of soapstone, a very soft mineral. It can be shaped easily, and a temperature treatment at roughly 1300 ?C, including diverse additives, will provide it with special properties. Advantages in comparison to ceramics: higher density better value concerning bending and compression strength as well as elasticity higher dielectric strength Other properties: non-inflammable temperature-resistant, dimensional stability up to 1000 ?C (housing may get in contact with hot objects, but the surrounding temperature should not exceed 200 ?C because otherwise, the scaling temperature of brass inserts will be reached)
