Grains

Grains make up the structure of metals. Metal surfaces contain a number of small crystals known as grains, with boundaries where they join. Abrasive grain material is prepared by coating non-sintered aluminum base particles with a metal alkoxide containing coating; heating to convert the coating to a metal oxide coating; and then sinter the base particles to provide sintered particles having an alpha-alumina-based core with an autogenously bonded metal oxide coating.
