PROCESS FOR PRODUCING A SHAPED BORON NITRIDE PRODUCT |
摘要 |
A process for the production of boron nitride is carried out by condensing a mixture of B-tris(loweralkylamino)borazine with an alkylamine in an inert gas atmosphere at a temperature of 150 DEG C or above to prepare a precursor, forming the precursor into a desired shape and then slowly heating the shaped precursor in an ammonia gas atmosphere until the precursor changes to a white boron nitride product. The shaped boron nitride in the form of a fiber is particularly useful as a reinforcement. |
