![عکس صفحه اول مقاله: Synthesis of nanosize BPO4 under microwave irradiation Synthesis of nanosize BPO4 under microwave irradiation](/preview/png/1489995.png)
Nanosize BPO4 was synthesized using H3BO3 and H3PO4 (85%) as raw materials under microwave irradiation. This reaction was performed at powers lower than 640 W and irradiation time ranging from 2.5 min to 5 min, which were only a fraction of the time required for conventional synthetic procedures. The structure of the as-prepared BPO4 is analogous to that of a high cristobalite. The particle sizes of the samples irradiated at 640 and 400 W range from 40 nm to 90 nm and 30 nm to 60 nm, respectively. The effects of different conditions on the experimental outcome are also discussed.

► Nanosize BPO4 are prepared under microwave-irradiation conditions.
► This reaction is only performed at less than 640 W power for 2.5–5 min.
► The particles of sample irradiated at 400 W are 40–90 nm in size and well dispersed.
► A simple, fast and green procedure for synthesis of nanosize BPO4 is developed.
