Calcined Alumina

Calcined alumina is a produced through the calcination of alumina to various temperatures, combined with state of the art process control equipment we have a range of high alpha alumina quality with controlled soda chemistry, surface area and size distributions.

Calcined alumina is generally used in manufacturing of high grade ceramic shapes, refractories and used to make parts that must withstand high temperature; Some exceptionally fine super ground grades are available which can be made into casting slurries of very specific gravity and which cast well with very low shrinkage; Alumina is added to glazed in the tile industry to impart matterness and texture, also for glazes that have a lot of melt fluidity, an addition of pure calcined alumina powder can stabilize the melt while maintaining most of the visual effect; Soda content is a major factor in determining the final use of electronic applications, medium soda for electrical insulation and porcelains, high soda for glass, glaze, fiberglass and electrical porcelain.
