A B S T R A C T The invention provides a method of making an abrasive product which comprises a layer of bonded ultra-hard abrasive particles bonded to a substrate. This abrasive product is typically a composite abrasive compact. The method includes the steps of: (a) providing a slurry of the components, in particulate form, necessary to make the layer of bonded ultra-hard abrasive particles in a liquid which contains a binder dissolved or dispersed therein; (b) providing the substrate which has side surfaces and an end surface to which the layer of bonded ultra-hard abrasive particles is to be bonded; (c) providing a container which is adapted to receive the substrate such that the side surfaces thereof form a close fit with the container; (d) placing a quantity of the slurry in the container; (e) inserting the substrate into the container such that the slurry is pressed between the container and the surface of the substrate to which the layer of bonded ultra-hard abrasive particles is to be bonded; (f) removing substantially all the liquid and binder from the slurry; and (g) subjecting the contents of the container to suitable elevated temperature and pressure conditions in the reaction zone of a high temperature/high pressure apparatus.
