【Abstract】 After research on the dispersion properties of nano-Si₃N₄ powder, the optimal parameter of dispersion technology is obtained. Experimental results show that the dispersion situation of nano-Si₃N₄ powder can be improved after nano-Si₃N₄ is carried out ultrasonic dispersion. The introduction of a certain amount of surfactant can enhance the dispersion effect of nano-Si₃N₄ powder. The effect of cationic surfactant is superior to that of nonionic surfactant. pH values of disperse system also have influence on the dispersion effect.更多还原
