Ceramics as material


Material of the future

Ceramics are often considered as the material of the future. Due to their excellent material properties ceramic materials gain increasing importance for research and industrial application. To date these materials have already been successfully implemented in everyday life. Ceramics can be found in many applications ranging from insulators in household appliances to the use in many areas of mechanical and electrical engineering.


Applications

High-performance ceramics possess exceptional mechanical properties in many respects. Hence, they are usually employed in environments where other materials fail (extreme temperatures, extreme mechanical loads, corrosive environments, extreme tribological stress, medical applications, etc). Fields of application include the automotive industry (e.g. diesel particulate filter), special machinery manufacture (e.g. textile industry), electrical engineering (e.g. functional ceramics), medical engineering (e.g. implants and dentures), jewellery (e.g. watch cases) and household (e.g. premium-quality mills).


Characteristics that distinguish ceramics from other materials:

  • High temperature resistance
  • High corrosion resistance
  • High wear resistance
  • Good tribological properties
  • Low density
  • High hardness
  • Low thermal expansion
  • Good electrical and thermal insulating properties
  • Excellent biocompatibility
