Abstract
Improved abrasive articles and methods for manufacturing such articles are disclosed. The articles include porous abrasive grains and abrasive wheels formed from such porous abrasive grains. Non-porous grains are formed from a mixture of abrasive material and burn-out material. Porous grains are formed then by removal of burn-out material when the non-porous grains are fired to form sintered porous abrasive grains. Grinding wheels and the like are then formed from the sintered porous abrasive grains.
