Preparation method of large-size hexagonal boron nitride and large-size hexagonal boron nitride
The invention relates to a preparation method of large-size hexagonal boron nitride and the large-size hexagonal boron nitride.The preparation method of the large-size hexagonal boron nitride comprises the steps that a hexagonal boron nitride seed crystal is prepared, then iterative growth is conducted on the basis of the hexagonal boron nitride seed crystal, and the large-size hexagonal boron nitride is prepared. According to the method, an iterative growth mode is adopted, growth continues on the basis of the prepared hexagonal boron nitride seed crystal, and finally large-size hexagonal boron nitride is obtained; the quality stability of the prepared large-size hexagonal boron nitride crystal grains is ensured, so that the large-size hexagonal boron nitride can meet the market demand of a high-thermal-conductivity low-dielectric-insulation boron nitride composite material; the hexagonal boron nitride seed crystal is continuously grown as a growth basis, so that the nucleation energy is reduced, the nucleation temperature of the large-size hexagonal boron nitride is reduced, the energy consumption in the production process is further reduced, and the preparation method of the large-size hexagonal boron nitride is low in operation difficulty, energy-saving and efficient.
