Abstract

BPO_4 was previously synthesized by the solid state reactions of (NH_4)_2HPO_4 and B_2O_3 at 1000 ^oC and was characterized by X-ray powder diffraction and IR methods. We have now succeeded in preparing BPO_4 from H_3BO_3 and P_2O_5 using hydrothermal synthesis by heating at 160 ^oC for 2 days and obtained a single phase product. We observed that a microwave-assisted synthesis takes only 3 to 5 minutes to transform a solid mixture of (NH_4)_2B_4O_7.4H_2O, and solid H_3PO_4 or B_2O_3 + P_2O_5 into the crystalline title compound. Its X-ray powder diffraction data and IR spectra were in good agreement with the literature values.
