Alumina (Aluminum Oxide)

Alumina (Aluminum Oxide),high hardness and wear resistance, low erosion levels, high temperature resistance

Alumina, also known as Aluminum Oxide, is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Once fired and sintered, it can only be machined using diamond-grinding methods. It features high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance, and bioinertness. Additionally, it can be highly polished making it useful for precision sealing applications like pumps and pistons.

Alumina is an excellent high temperature ceramic material due to its high temperature stability. It is the most commonly used type of advanced ceramic and is available in purities ranging from 95 – 99.9%. Precision Ceramics has access to many different types of Alumina including: injection molded, die pressed, isosostatically pressed, slip cast, and extruded.

 

 

 

 

Alumina Properties

Alumina features high hardness and wear resistance, low erosion levels, high temperature and corrosion resistance and bio-inertness. Its high temperature stability and thermal conductivity make it particularly suitable for high temperature applications such as thermocouple protection in high temperature measurement.

  • Excellent electrical insulation properties
  • High compressive and dielectric strength
  • High hardness and mechanical strength
  • High thermal conductivity and thermal shock resistance
  • Low density
  • Resistant to strong acid and alkali attack at high temperatures
  • Transparent to microwave radio frequencies
  • Very specific thermal conductive and thermal expansion rates
  • Wear and abrasion resistant

Alumina is available is multiple grades including 95%-99.9% high purity Alumina, high purity re-crystalized Alumina, and Zirconia toughened Alumina (ZTA). The following are the properties for 99.7% grade alumina.
