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
