A method of producing an abrasive compact material includes providing a source of cBN particles, coating the cBN particles with one or more aluminium or titanium compounds, in particular aluminium nitride, aluminium boride, titanium nitride and/or titanium boride, and sintering the coated cBN particles with nanosized alumina at a temperature less than 1550°C. The sintering process is carried out in air at atmospheric pressure. |
