Abstract
The invention provides for an ultra hard or hard composite material comprising a primary ultra hard or hard particulate material and at least one secondary ultra hard or hard particulate material dispersed in a matrix material. The primary ultra hard or hard particulate material has a thermal expansion coefficient lower than that of the matrix material and the at least one secondary ultra hard or hard particulate material has a thermal expansion coefficient greater than that of the matrix material.
