PRECURSOR OF ALUMINA SINTERED BODY, METHOD FOR PRODUCING ALUMINA SINTERED BODY, METHOD FOR PRODUCING ABRASIVE GRAINS, AND ALUMINA SINTERED BODY
A precursor of an alumina sintered body contains aluminum, yttrium and at least one metal selected from the group consisting of iron, zinc, cobalt, manganese, copper, niobium, antimony, tungsten, silver and gallium, and which is configured such that: the content of the aluminum is 98.0% by mass or more in terms of oxide (Al2O3) in 100% by mass of the precursor of an alumina sintered body; the content of the yttrium is 0.01-1.35 parts by mass in terms of oxide (Y2O3) relative to 100 parts by mass of the content of the aluminum in terms of oxide; the total content of the metals selected from theabove-described group is 0.02-1.55 parts by mass in terms of oxides relative to 100 parts by mass of the content of the aluminum in terms of oxide; and the aluminum is contained in the form of alpha-alumina.
一种氧化铝烧结体的前体，包含铝、钇以及选自由铁、锌、钴、锰、铜、铌、锑、钨、银和镓组成的群组中的至少一种金属，在所述氧化铝烧结体的前体100质量％中，所述铝的含量按氧化物(AlO)换算计为98.0质量％以上，相对于所述氧化物换算的铝的含量100质量份，所述钇的含量按氧化物(YO)换算计为0.01～1.35质量份，相对于所述氧化物换算的铝的含量100质量份，选自所述群组中的金属的合计含量按氧化物换算计为0.02～1.55质量份，所述氧化铝烧结体的前体以α‑氧化铝的形式包含所述铝。
