CALCINED BAUXITE SANDBLASTING / REFRACTORY

Non-fused aluminum oxide with a lower hardness & good toughness properties. Suitable for sandblasting that allows lower: efficiency, pricing point, BD, and limited sizes.

Product code: OM-CB

Description

Calcined bauxite does not belongs to the group of electro-corundum, as it is neither smelted nor fused. It is calcined in a rotary kiln at a high temperature (~ 1500 °C) to extract water, which increases its hardness.
