Bauxite sand

Bauxite sand is mainly (75%) composed of aluminium oxide (Al2O3).

This synthetic sand presents excellent refractory properties and a thermal expansion similar to Chromite sand.

It is marketed in different sizes though normally supplied with 65 AFA size and 2 g/cm3 bulk density.

Its magnetic properties enable its separation from silica sand.

Furthermore, Bauxite sand gives high mechanical strength to moulds in Cold Box, Hot Box and No-bake furan systems.

It is often used as Zirconium sand substitute in steel applications.
