Method for Preparation of New Superhard Boron Carbonitride Material

Method for preparing superhard ternary boron carbonitride compound Advantages . Produces a superhard ternary boron carbonitride compound . Requires temperature and pressure conditions achievable in existing industrial high pressure devices . Produces BC0.5N at >70% yield Technology The method of this invention uses relatively low temperature and pressure conditions (1400-1600ºC and 7.5-8.5 GPa) to produce superhard BC0.5N. This is a dramatic improvement over the only known process for the preparation of this material, which is carried out at >25GPa pressure and >1800º C and requires equipment not practical for large scale manufacture. The resulting superhard BCN material has a hardness second only to diamond and is expected to be more thermally and chemically stable than diamond. Potential Applications . Manufacturing tools, such as drill bits, cutters, saws, and abrasives, used for handling tough alloys or composites or in microelectronics, as well as for oil and gas exploration and mining. Patent Status . A provisional patent application has been filed with the US Patent and Trademark Office The Inventors Dr. Valery Khabashesku is a Faculty Fellow in the Department of Chemistry and the Richard E. Smalley Institute of Nanoscale Science and Technology at Rice University. Dr. Khabashesku has been a visiting scientist/ professor with the U.S. National Academy of Science at universities across the U.S. and an invited lecturer at various international symposia, workshops and industrial meetings. In 2001 he was named a Laureate of the State Prize of the Russian Federation in science and technology, the nation�s highest civilian honor.
