description The invention provides a synthesis method for regulating and controlling crystal face orientation of melamine cyanurate. The preparation method comprises the following steps: adding melamine, a dispersing agent, a solvent and a pH regulator into a reaction kettle, and stirring at a high speed at a certain temperature to obtain a high-dispersion ME precursor solution; then cyanuric acid is added into the ME precursor solution, after the reaction temperature is kept and stirring is conducted for a period of time, a crystal face inducer is added, stirring is continuously conducted for a constant-temperature reaction, suction filtration, washing, drying and smashing are conducted after the reaction is completed, and MCA with specific crystal face orientation is obtained. By adding the crystal face inducer, the effects of inhibiting (110) and (200) crystal faces, inducing (220) crystal face growth, interfering formation of an MCA large-plane hydrogen bond network, limiting infinite extension of the hydrogen bond n
