Materials Science: Tutorials: Ceramics

Most refractories are made up of coarse oxide particles bonded by finer refractory particles. During firing, the fine particles form the bonding phase. Abrasives are used to wear, grind and cut away other materials. Abrasives make use of the hardness and wear resistance of ceramics, but they also require a minimum toughness so that the abrasive particles don't fracture on impact. Diamond is ...
