Claim 0:
1. A method of producing a polycrystalline diamond (PCD) body, comprising the steps:
a. Forming a precursor binder mixture of FexN and graphite powders;
b. Adding the precursor binder mixture to a refractory cup in a layer;
c. Adding a diamond feed stock to the cup, adjacent to the precursor binder mixture;
d. Compacting the precursor binder mixture and diamond feed stock in the cup to form a green body;
e. Sintering the green body at a temperature of 1700° C. to 2300° C. and at a pressure of about 7 GPa, or higher for at least 30 seconds to form a sintered PCD body.
