Material
Technical ceramics have some outstanding features, such as temperature resistance, wear resistance, hardness, biocompatibility and also insulating properties. In our opinion, there is no need for more arguments in favor of this material.
The right composition for every application
With ceramic components, it is the mixture that is most important. The properties of technical ceramics can be specifically influenced and improved for special areas of application: With a suitable selection and fine-tuning of the material composition, our material is even better adapted to the environmental conditions. The foundations of every product made of technical ceramics are the finest, high-purity powders and binder systems, which are sintered into a finished component in a high-temperature furnace. By varying the powders and developing its own binder systems, Bosch Advanced Ceramics has perfected its materials.
Unbeatable properties
Hardness
The extreme hardness of technical ceramics makes them suitable for high pressure loads and adverse conditions.
Thermal conductivity
Technical ceramics have a thermal insulating effect.
Thermal stability
When low expansion is required, technical ceramics are the material of choice.
Corrosion resistance
Technical ceramics are resistant to many chemicals such as acids and alkalis and are therefore corrosion-resistant.
Low friction
Low friction and heat generation ensure the best possible tribological properties.
Electrical insulation
Technical ceramics have an electrically insulating effect.
Unbeatable properties
Wear resistance
The excellent mechanical properties of technical ceramics ensure low abrasion and a long service life even under heavy loads.
High-temperature strength
The heat resistance extends to well over 1000°C – for high-temperature applications, technical ceramics are therefore often the only alternative.
