Alumina ceramic
Alumina ceramic is akind of ceramic material with alumina(Al2o3)as the main body,which has the characteristics of high hardness,high strength,high wear resistance,high corrosion resistance,high temperature resistance and strong insulation.
The
two
most
commonly
used
ceramic
materials
are
95%
alumina
and
9%
alumina:
(1)95%
alumina:Because
ofits
excellent
performance,95%
aluminais
widely
used
in
grinding
and
polishing
processes,
as
wel
as
in
the
chemical
and
metalluraical
industries.
Mainly
used
as
corrosion-resistant
and
wear-resistant
parts.
(2) 99% alumina:99% alumina has high strength and can be used to make high-temperature crucibles,refractory furnace tubes and special wear-resistant materials, such as ceramic pumps, boltimellers,ceramicrollers,ceramicsealsandwatervalves.
