摘要
A dental blank is provided for yielding a metal frame having a desired shape according to a dental CAD/CAM system and a machining process. The dental blank is formed from a metal powder sintered body and contains Co as a main component, Cr in a proportion of 26% by mass or more and 35% by mass or less, Mo in a proportion of 5% by mass or more and 12% by mass or less, and Si in a proportion of 0.5% by mass or more and 1.0% by mass or less. Further, part of the Si is silicon oxide, and the ratio of the silicon oxide to the total amount of Si is preferably 10% by mass or more and 90% by mass or less.
