USE AS A FLOW IN THE PREPARATION OF CUBIC BORON NITRIDE OF A FLUORONITRIDE AND PROCESS FOR THE PREPARATION OF CUBIC BORON NITRIDE USING SUCH A FLOW

摘要

USE AS A FLOW, IN A PROCESS FOR OBTAINING CUBIC BORON NITRIDE, OF A FLUORONITRIDE; AND METHOD OF OBTAINING CUBIC BORON NITRIDE, FROM A SOURCE OF BORON AND FROM A SOURCE OF NITROGEN, IN THE PRESENCE OF A FLUORONITRIDE OR A SOURCE OF FLUORONITRIDE, AT A PRESSURE CORRESPONDING TO THE FIELD OF ' EXISTENCE OF CUBIC BN, AND AT A SUFFICIENT TEMPERATURE FOR A LIQUID PHASE TO APPEAR.
