Polycrystalline diamond body, cutting tool, wear-resistant tool, grinding tool, and method for producing polycrystalline diamond body
A polycrystalline diamond body contains diamond particles. The diamond particles have a mean particle size of 50 nm or less. As a result of measurement of a knoop hardness under a test load of 4.9 N at 23° C.±5° C., the polycrystalline diamond body has a ratio of a length B of a shorter diagonal line with respect to a length A of a longer diagonal line of diagonal lines of a knoop indentation, expressed as a B/A ratio, of 0.080 or less. This polycrystalline diamond body is tough and has a small particle size.
