Abstract: A method of producing a free standing PCD comprises forming a mass of combined diamond particles and precursor compound(s) for the metals of the metallic network by suspending the diamond particles in a liquid, and crystallising and /or precip -itating the precursor compounds in the liquid. The mass is then removed from suspension by sedimentation and/or evaporation to form a dry powder of combined diamond particles and precursor compound(s). The powder is subjected to a heat treatment to disso -ciate and reduce the precursor compound(s) to form metal particles smaller in size than the diamond particles to provide a homogen -eous mass. This is then consolidated using isostatic compaction to form a homogeneous cohesive green body of a pre-selected size and 3-dimensional shape.

Abstract: A free standing PCD body comprises a PCD material formed of combination of intergrown diamond grains forming a diamond network and an interpenetrating metallic network, the PCD body not being attached to a second body or substrate formed of a different material. The diamond network is formed of diamond grains having a plurality of grain sizes, and comprises a grain size distribution having an average diamond grain size, wherein the largest component of the diamond grain size distribution is no greater than three times the average diamond grain size. The PCD material forming the free standing PCD body is homogeneous, such that the PCD body is spatially constant and invariant with respect to diamond network to metallic network volume ratio. The homogeneity is measured at a scale greater than ten times the average grain size and spans the dimension of the PCD body. The PCD material is also macroscopically residual stress free at said scale.
