<p>The present invention provides a diamond sintered compact having a higher strength as well as better heat, breakage and corrosion resistance than the compacts of the prior art, which can thus be effectively applied to tool materials for cutting or polishing non-ferrous metals or ceramics, and to edge materials for drill bits for petroleum excavation. The diamond sintered compact comprises 0.1 to 30 volume % of at least one compound which comprises oxygen and at least one element selected from silicon and titanium, and the balance of diamond, for example, a titanate of a metal selected from iron, cobalt, nickel and manganese.</p> |
