  • Bauxite: The principal ore of aluminum. Geology

    Sintered bauxite is often used as a sand-blasting abrasive. It is produced by crushing bauxite to a powder and then fusing it into spherical beads at a very high temperature. These beads are very hard and very durable. The beads are then sorted by size for use in different types of sandblasting equipment and for different sandblasting applications. Their round shape reduces wear on the delivery equipment.
