PURPOSE:To enable the easy formation of a grindstone and a cutter without any application of pressure by using extra-fine grains generated from the hydrolytic reaction of metal alkoxide as bonding material grains. CONSTITUTION:Metal alkoxide and aqueous solution 1 mixed with water and chemicals for facilitating hydrolysis are stirred with an agitator 3 for the formation of a mixed fluid 8. This fluid 8 is poured into a mold 4 and dried naturally for the removal of water, alcohol and the like therefrom. Thereafter, the fluid 8 so dried is released from the mold 4 as a mixture 5. This mixture 5 is sintered in a small-sized heat treatment furnace, thereby obtaining a desired grindstone 6. |
