A nonmetallic material, which is manufactured
by forming and baking, is called ceramics.
There are general-purpose
ceramics using a container characteristic
like chinaware, cement and glass. Then there
are the fine ceramics, excellent
in optical characteristic, thermal characteristic,
or the mechanical property.
Alumina is the material used. The Alumina
(AL), which is metal connected with oxygen
(O), have been joined together
at a rate of 2 to 3 with the aluminum
oxide, and the chemical formula as AL 203.
Alumina, which represents ceramics, and
there is it from 10 % of containing percentage
to the high nine-amount
purity article but our company insert
is using 96% alumina. Alumina material is
used for IC boards, an insulator
for electric insulation material, rollers,
mortar, pump goods for machine parts, bearings,
gears, melting pots,
artificial bones, and much more..
