Alumina is the most mature of the engineering ceramics, offering
excellent electrical insulation properties together with high
hardness and good wear resistance but relatively low strength and
fracture toughness.
During the prodcution, small amounts of silica (SiO2), magnesia
(MgO) and zirconia (ZrO2) may be added to alumina ceramics. The
applications vary with the purity of Alumina.*9% Alumina Ceramics
are mostly used for high temperature crucibles, kiln furniture,
special abrasion resistant parts, such as ceramic bearings, ceramic
sealings or faucet discs; *5% Alumina Ceramics are usually applied
for corrosion-resitant components or wear proof parts; *5% Alumina
Ceramis can be metallized with metals like molybdenum, niobium,
tantalum to use for electric vacuum devices.
Properties of Alumina Ceramics
Alumina has a high melting point, high hardness and high mechanical
strength, although mechanical strength is reduced at temperatures
above ***0°C. Due to the relatively large coefficient of thermal
expansion, thermal shock resistance is reduced. Alumina is an
electrically insulating material, with a high electrical
resistivity, increasing with purity.Good chemical stability of
alumina, leads to a high corrosion resistance. It is insoluble in
water and only slightly soluble in strong acid and alkaline
solution.
Various Application of Alumina Ceramics
1.Seal rings
2.Medical prostheses
3.Laser tubes
4.Electronic substrates
5.Ballistic armour
6.Thermocouple tubes
7.Electrical insulators
8.Grinding media
9.Threadguides
*0.Wear components
