Industrial grade 99 % alumina content high-purity superfine special for ceramics activated alumina
The production process of alumina powder :
Alumina powder is made of bauxite, the main ore of aluminum. The
bauxite consists of a mixture of gibbsite, boehmite, iron oxide,
iron hydroxide, quartz and clay minerals. Alumina is extracted by
the Bayer process, in which the chemical composition AL2O3 ( active
alumina powder ) is distilled from the bauxite mixture. The unique
characteristics that make alumina the ideal choice for aluminum
production, especially those applications that require hardness and
wear resistance or other forms of chemical wear. Activated alumina
powder is also an ideal choice for products that require corrosion
resistance and wear resistance, as well as products that require
high thermal conductivity ( such as electrical insulation and
thermal insulation applications ).
Properties of alumina powder :
Alumina has a relatively high melting point and boiling point, as
well as a very high hardness level. Its mechanical strength and
compressive strength are higher than many materials. Its
resistivity and thermal conductivity make alumina an ideal choice
for many electrical products.
