A kind of boron nitride precursor was prepared by a wet chemical approach using ammonium meta-borate and melamine as raw material. To get an insight into the synthesis process of boron nitride precursor, the effects of melamine to ammonium meta-borate molar ratio and the total concentration of solution were respectively investigated. The results showed that a better precursor was synthesized by making use of the molar ratio of 1:1 for the melamine and ammonium meta-borate and the total solution concentration of 0.5 mol/L for the reactants. The precursor were charac-terized by FT-IR, XRD, chemical composition, element analyze and SEM analyses, and the analysis results indicat-ed that the precursor was a supramolecular adduct formed by intermolecular hydrogen bonds and the morphology of pre-cursor that was determined the molecular composition of C3N6H6·2H3BO3 exhibits a rod-like crystals. Then the synthet-ic precursor was treated at 950℃for 4h in the air to yield good crystals of hexagonal boron nitride powder .
