   Synthesis of six square boron nitride nanoscale.


boron nitride

     A method for the synthesis of six square boron nitride nanoscale, the method comprises the following steps: (1) mixing the boron nitride nanospheres with the metal chloride for 0.5-3 hours and stirring the mixed powder; (2) the mixed powder obtained in the step (1) is heated to 600-1400 centigrade at a rate of 1-30 C / min at a temperature of 1-30 at a protective atmosphere and then maintained. The heat treatment was carried out at 1-6 hours, and then decreased to room temperature in the protective atmosphere. After the product was washed, the six boron nitride nanosheets were cleaned. By introducing metal chloride as mineralizer, the six square boron nitride nanospheres can be transformed into boron nitride nanoscale at a lower temperature (600~700 C). The preparation temperature of the invention is lower than that of the existing boron nitride nanosheets, which is about 1000 degrees lower than that of the existing boron nitride nanosheets, thereby greatly reducing the energy consumption in the preparation process.
