ELECTROFUSED ALUMINA GRAINS, PRODUCTION METHOD FOR ELECTROFUSED ALUMINA GRAINS, GRINDING STONE, AND COATED ABRASIVE
Provided are electrofused alumina grains excellent in grinding performance and a production method of such electrofused alumina grains, and a grinding stone and a coated abrasive using the electrofused alumina grains. The electrofused alumina grains of the present invention contain titanium and magnesium. The production method for the electrofused alumina grains includes the steps of: preparing a mixture material by mixing an alumina material, a titanium compound and a magnesium compound, forming an ingot from the mixture material according to an electrofusing process, grinding the ingot to prepare a ground powder, size-regulating the ground powder to have a predetermined grain size to prepare size-regulated grains, and heating the size-regulated grains at a heating temperature of 1,000° C. or higher to give electrofused alumina grains. The grinding stone contains the electrofused alumina grains. The coated abrasive contains the electrofused alumina grains.
