Hydrothermal and microwave-assisted synthesis of boroarsenate, $BAsO_4$

$BAsO_4$ was previously synthesized by solid-state reactions at 800 ◦C and was characterized by X-ray powder diffraction. Now, we succeeded in preparing $BAsO_4$ from $H_3BO_3$ and $As_2O_5$ using hydrothermal synthesis by heating at 160 ◦C for 3 days (a single-phase product) and using microwave-assisted synthesis, which takes only 5 min to transform a solid mixture of $As_2O_5$ and $(NH_4)_2B_4O_7.4H_2O into the crystalline titled compound (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.
