What is Silicate Ceramics and where is it used?
Early developments in the field of technical ceramics began with the use of silicate ceramics for electrical insulation. Silicate ceramics are manufactured for the most part from natural raw materials. Silicate ceramics such as mullite, cordierite, steatite or aluminium silicate - used creatively and intelligently - open up impressive cost-cutting potential and are used in numerous applications in electronics, energy and environmental technology where reliable insulation and thermal resistance are required.
By varying the type and quantity of raw materials, multiphase ceramic types with the desired material properties can be produced. The materials of silicate ceramics include:
- Porcelains: Alkali – aluminium silicates (Type C130, C140)
- Steatites: Magnesium silicates (Type C220, C221 and C230)
- Cordierites: Alkaline earth – aluminium silicates (Type C410, C520 and C530)
- Mullites: Aluminium oxide – silicon oxide compositions (Type C610, C620/C780)
To ensure that the enhanced properties of ceramic materials are fully exploited, CeramTec's silicate technology designers don't just think in terms of products - they think in terms of system solutions. Their expertise in the manufacture and integration of silicate ceramic components helps them to develop creative, ceramic-oriented solutions for every application.
Highly efficient manufacturing technologies enable the production of difficult-to-design products with maximum precision, even in high volumes. CeramTec also performs finishing and assembly work on complex components and supplies ready-to-install silicate ceramic components for cost-saving system solutions.
