Abstract

Novel monodispersed peanut-type SrSO₄ (celestine) particles have been prepared using a facile precipitation reaction of Sr-EDTA chelating precursors at ambient temperature. The as-formed products were studied by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen absorption-desorption and differential scanning calorimetry-thermogravimetry (DSC-TG) measurement. The monodispersed SrSO₄ particles with an average length of 1.7 μm and an aspect ratio of 1.4 appear unusual peanut-type morphology. These SrSO₄ particles have a relatively large Brunauer-Emmett-Teller (BET) surface area of about 20.9 m² g^-1 and contain mesopores with a mean pore size of about 34.3 nm. The SrSO₄ particles exhibit an excellent thermal stability from room temperature to 1400 °C with a structural transformation at 1158.3 °C. The growth mechanism of the monodispersed peanut-type celestine particles was discussed to obtain a better understanding on their formation process.
