| titleOfInvention | Process for continuous production of boron nitride powder |
| abstract | The present invention provides a process for continuously producing crystalline hexagonal boron nitride powder having a large particle size and high crystalline. The present invention relates to a process comprising: the first step of heating a boron-containing material and a nitrogen-containing material to obtain crude boron nitride powder having boron nitride content of 80% by weight or higher, and the second step of feeding the crude boron nitride powder and a boron-containing flux component in the content satisfying the following formula (1) with a heat-resistant container, and heating the container including the crude boron nitride powder and the boron-containing flux component at 1550 to 2400° C. in a continuous furnace under the atmosphere of nitrogen gas, to grow hexagonal boron nitride in the form of crystal: formula (1): boron content contained in boron-containing flux component/crude boron nitride content ≦1.4 % by weight. |
