Abstract

PURPOSE:To produce a diamond sintered body under a relatively low press. in a short time by sintering raw material diamond powder having a microstrain, at high temp. and press., obtd. by applying mechanically striking energy. CONSTITUTION:Diamond powder 1 with an average diameter of 30mu or less is covered with Ni foil, formed into a disk, and set on central protrusion 4 of lower punch 3 fixed into cylinder 2, and upper punch 5 is mounted on the disk. Striking energy of 10 tons.meter or more is applied to powder 1 through punch 5 to produce a microstrain inducing no change in crystal external form and having crystal disorder or lattice disorder in the interior alone. Powder 1 having the microstrain is then sintered as a starting raw material with a usual static high press. unit under above 55000 atm at above 1300 deg.C for about 5min to obtain a diamond sintered body. By further holding this body at constant high temp. and press. diamond can be grown.
