Manufacturer Advanced Ceramics Parts and Components, advanced ceramic components, technical ceramic parts

Technical Ceramics" "Engineered Ceramics" or "Advanced Ceramics" can arguably be defined by function or by their material make-up. For example: you take a piece of clay (a non-"technical" material) and use it in a "technical" application and thus you have a "technical ceramic". However, most would argue that a "technical" ceramic is defined by its material composition, more so than its application. So if you are going to go the "material composition" route, a technical ceramic is a ceramic material that is derived from the same minerals that you can derive metals from. Example: If you take Bauxite, which is a mineral you dig up out of the ground, and make a metal out of it...you get aluminum metal. If you take Bauxite and derive a ceramic from it...you get aluminum oxide ceramic. If you take zircon sand, you get zirconium metal. If you derive a ceramic from zircon sand...you get zirconia ceramic. So, a technical ceramic can be defined by its application, but usually is defined by its chemical make-up. In simplistic terms for our forum here, a technical ceramic is a ceramic material that is derived from the same minerals that you can get metals from. While there are endless combinations of ceramic materials that can be derived, 99.9% of the technical ceramics that you will encounter are based upon the oxides, nitrides and carbides of various minerals, but primarily aluminum, zirconium and silicon.

1. Advanced ceramics

  • low density
  • high hardness
  • high mechanical strength
  • dimensional stability (specific stiffness)
  • resistance to wear
  • resistance to corrosion (resistance to chemical attack)
  • weathering resistance
  • high working temperature
  • low or high thermal conductivity
  • good electrical insulation
  • dielectric and ferroelectric properties

2. The most popular advanced ceramic materials:

ALUMINA (al2o3), ZIRCONIA (zro2), SILICON CARBIDE (sic), SILICON NITRIDE (si3n4), ALUMINIUM NITRIDE (ain), BORON NITRIDE (b4c) etc..
