Description
Sintered or Calcined Bauxite A spherical abrasives made from bauxite, a clay – like ore of hydrated aluminium oxide, are often used as alternatives to aluminium oxide because they are cheaper. The abrasive is produced by heat-treating natural bauxite without melting and fusing it (as in the manufacture of aluminium oxide).
Example – Sintered bauxite shot is used in memorial masonry trade for lettering gravestones.
