A new route including precipitation combined with calcination has been developed for the synthesis of strontium orthosilicate (Sr2SiO4) nano-sized particles. The stirring of the boiling aqua suspension prepared from hydrosilicagel derived from serpentine minerals ((Mg(Fe))6[Si4O10](OH)8), sodium hydroxide (NaOH) and strontium chloride (SrCl2) results in the precipitation of hydrated strontium silicate species whose dehydration is followed by their crystallization into strontium ortho- and metasilicate SrSiO3 on heating. The stirring time and sodium hydroxide concentration are the key parameters controlling strontium silicates formation. The influence of these parameters on the precipitates formation and their phase transformations at various temperatures has been studied by X-ray diffraction, thermal analyses and electron microscopy. The optimal parameters, namely the molar ratio of initial reagents, stirring time, the temperature and duration of heat treatment providing strontium orthosilicate synthesis, have been suggested. The average particle size of strontium orthosilicate synthesized by this method is 20–40 nm.
