Advanced Ceramics

Material

The Right Composition for Each Application

For ceramic components, the composition of the material is crucial. With Technical Ceramics, these properties can be specifically modified and enhanced for specific cases. By choosing and adjusting the suitable material composition, the material can be perfectly adapted to the ambient conditions. The basic component of any Technical Ceramics product are the binding agents and the pure, fine powder, which are sintered in a high temperature furnace to become a finished component. By varying the powder and developing proprietary binding agents, Bosch Advanced Ceramics has brought its materials to perfection.

Properties of Technical Ceramics

High Temperature Resistance

The heat resistance reaches far beyond 1000°C - Technical Ceramics are thus often the only alternative for high temperature applications.

High Wear Resistance

The excellent mechanical properties of Technical Ceramics ensure minimal abrasion and long service life, even under harsh conditions.

Hardness

The extreme hardness of Technical Ceramics makes them suitable for handling high pressure and adverse conditions.

Chemical Resistance

Technical Ceramics are resistant to many chemicals such as acids and brines, and are therefore noncorrosive.

Good Insulation Properties

Technical Ceramics display both electrical and thermal insulation properties.

Biocompatibility

Technical Ceramics are suitable both for the medical and food sectors: the materials are 100% compatible with the human body.

Available Materials

Aluminum Oxide

AI203

Overview of Material Properties

The properties are to be regarded as indicative values, which are transferable to real components only to a certain extent. We therefore cannot assume any liability for these parameters in practical application cases. The parameters of the end product depend on the production process, component geometry and powder particle size. We are glad to provide our expertise to assess the suitability of a material for your practical application.
