PRECURSOR OF ALUMINA SINTERED BODY, METHOD FOR PRODUCING ALUMINA SINTERED BODY, METHOD FOR PRODUCING ABRASIVE GRAINS, AND ALUMINA SINTERED BODY
The present invention relates to a precursor of an alumina sintered compact including aluminum, yttrium, and at least one metal selected from the group consisting of iron, zinc, cobalt, manganese, copper, niobium, antimony, tungsten, silver, and gallium, wherein the content of the aluminum is 98.0% by mass or more as expressed in terms of an oxide (Al2O3) in 100% by mass of the precursor of an alumina sintered compact; the content of the yttrium is 0.01 to 1.35 parts by mass as expressed in terms of an oxide (Y2O3) based on 100 parts by mass of the content of the aluminum as expressed in terms of an oxide; the total content of the metals selected from the foregoing group is 0.02 to 1.55 parts by mass as expressed in terms of an oxide based on 100 parts by mass of the content of aluminum as expressed in terms of an oxide; and the aluminum is contained as α-alumina.
