The advantages are obvious


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.

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, 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


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.

Our materials portfolio


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


  • Wear parts for the textile and the machine engineering industry
  • Suitable for high temperatures and corrosive environments, e.g. in laboratories
  • Insulating parts for electronics and electrical engineering


  • Electrical insulation
  • Thermal resistance
  • Hardness
  • Pressure resistance


Zirconia has the unique feature that it impedes the spread of cracks through the so-called transformation toughening mechanism. No other ceramic material shows such a high fracture toughness combined at the same time with such high stability.


  • Sensor Technology (lambda sensors) for oxygen ion conduction
  • Components that face frequent temperature changes, e.g. draw dies and high-temperature insulating parts
  • In cases where high fracture toughness is required, e.g. for medical instruments


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


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


  • Bearings and guide parts for machine engineering
  • Surgical instruments


  • Thermal insulation
  • Flexural Strenth
  • Electrical insulation
  • Temperature and thermo shock resistance
  • Fracture toughness


With this mixture of ceramics, a small amount of zirconia is added to the aluminum oxide which significantly improves the stability and simultaneously increases the toughness.


  • Cutting materials for machine
  • Valves, gear wheels
  • Sensors
  • For highest mechanical loads


  • Hardness
  • Resistance to pressure
  • Resistance to thermal shock
