Abstract :BAsO4 was previously synthesized by solid-state reactions at 800 °C and was characterized by X-ray powder diffraction. Now, we succeeded in preparing BAsO4 from H3BO3 and As2O5 using hydrothermal synthesis by heating at 160 °C for 3 days insert ignore into journalissuearticles values(a single-phase product); and using microwave-assisted synthesis, which takes only 5 min to transform a solid mixture of As2O5 and insert ignore into journalissuearticles values(NH4);2B4O7.4H2O into the crystalline titled compound insert ignore into journalissuearticles values(a single-phase product);. The crystallinity of the products is higher than that of the solid-state synthesized product given in the literature. Its X-ray powder diffraction patterns, and both Raman and IR spectra were in good agreement with the literature.
