The advantages are obvious

Material

Technical ceramics are not cheap, but they are valuable, temperature-resistant, wear-resistant, hard, insulating and biocompatible. In our opinion, there is no need for more arguments in favour of this material.

Ceramic powder, additive and feedstock

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, your 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 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.

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.

Our materials portfolio

Aluminium oxide

AI203

The material has a uniquely diversified range of applications because of its numerous degrees of purity. We offer aluminum oxide with a purity ranges from 96.0% to 99.8%.

  • In cases where high fracture toughness is required, e.g. for medical instruments

Properties

  • Thermal insulation
  • Thermal resistance
  • Flexural Strength
  • Electrical insulation
  • Fracture toughness

Alumina Toughened Zirconia (ATZ)

ATZ

With this kind of mixed ceramic, a small amount of aluminum oxide is added to the zirconium oxide to significantly improve the wear-resistance, elasticity and toughness.

Application

  • Bearings and guide parts for machine engineering
  • Medical implants
