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.
