Key Words are: alumina ceramic tiles, alumina tiles, alumina ceramic
plates, alumina wear ceramic lining plates
Wear resistant alumina tiles are sintered on high temperature of more than 1530℃,
with high-purity ultra-fine alumina powder as raw material according to
optimized formulation design, they have the following properties:
(1) Hardness mohs 9, is only second to that of the diamond
(2) Perfect wear resistance, 260 times that of Manganese Steel and 170 times
that of Chromium Steel in theory
(3) Resistance to high temperature, when pasted on the inner wall of
equipment with heat-resisting adhesive, they can operate for a long time
without aging at temperature of 350℃
(4) Convenient construction to reduce cost and avoid downtime
(5) As equipment liner, their density is only half of the steel which can reduce
the load of equipment largely.
