A technique for producing new grades of submicron and nanosized powders of cubic boron nitride (cBN) is developed. It includes preliminary treatment of powders and their surface modification to control the hydrophilic–hydrophobic balance. Processes are developed for producing submicron and nanosized powders of cubic boron nitride that change their hydrophilic–hydrophobic balance. Thermal treatment in inert environments makes the surface of cBN powders hydrophobic and electrochemical treatment makes it hydrophilic. New grades of submicron and nanosized powders of cubic boron nitride are created. Hydrophobic KSM-F and KN-F powders are recommended for the production of polycrystalline materials and tools on their basis and hydrophilic KSM-É and KN-É powders for composite coatings, suspensions, and pastes.
