Alumina Ceramics Description

Alumina ceramics can be divided into several application grades according to their alumina content, of which 99% alumina porcelain materials are used to make high-temperature crucibles, refractory furnace tubes, and special wear-resistant materials, such as ceramic bearings, ceramic seals, and water valve pieces; 95%-96% alumina porcelain is mainly used as corrosion-resistant, wear-resistant components, and circuit substrates.

Alumina Ceramics Properties

  • Excellent electrical insulation (1 x 10 14 to 1 x 10 15 Ω cm).
  • Medium to ultra-high mechanical strength (300 to 630 MPa).
  • Very high compressive strength (2000 to 4000 MPa).
  • High hardness (15 to 19 GPA).
  • Medium thermal conductivity (20 to 30 W / MK).
  • high corrosion and wear resistance.
  • good abrasive properties.
  • low density (3.75 to 3.95 g / cm3).
  • Operating temperatures of 1000 to 1500°C without mechanical load.
