Nanoscale SrHPO4 is prepared via a polyol-mediated synthesis. The resulting particles are well crystallized, non-agglomerated, and very uniform in size and shape. By adjusting the experimental conditions, SrHPO4 can be obtained with the alpha-type as well as with the beta-type of modification. In particular, particle diameters of 16 nm (alpha-SrHPO4) and 12 mn (beta-SrHPO4) are obtained. The title compound is characterized by scanning electron microscopy, dynamic light scattering, X-ray powder diffraction, and infrared spectroscopy.
