Alumina and Alumina Refractories – IspatGuru
Jan 25, 2015· Another way to produce these refractories is to use a mixture of bauxite and fireclay. This latter method is called the bauxite dilution method since the bauxite (at 88 % Al2O3) is diluted with calcined fireclay and raw clay (contains around 40 % Al2O3) to produce the required Al2O3 content.
Bauxite
In the bauxite refining process, the aluminumbearing minerals in bauxite are converted in a multiplestep process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line hightemperature rotary kilns and metallurgical furnaces.

Bauxite Facts
Bauxite is used as an abrasive. Sintered bauxite is often used as a sandblasting abrasive produced by crushing bauxite to a powder, and then fusing it using a very high temperature into spherical beads. The bauxite spherical beads are very hard and durable. They are sorted by size for use in sandblasting equipment and other sandblasting ...
