ABSTRACT:
The present invention provides a diamond sintered compact having a higher strength as well as more excellent heat resistance, breakage resistance and corrosion resistance, as compared with those of the prior art, which thus can effectively be applied to tool materials for cutting or polishing of non-ferrous metals or ceramics, and edge materials of drill bits for excavating petroleum. The feature of the diamond sintered compact contains 0.1 to 30 volume % of at least one compound containing at least one element selected from the group consisting of silicon and titanium, and oxygen and the balance of diamond, for example, a titanate of a metal selected from the group consisting of iron, cobalt, nickel and manganese.
