Abstract

Irregular strontium silicate powders with high purity were synthesized by sol-gel process using TEOS and Sr (NO₃)₂ as raw materials. The effects of strontium salt types (SrCl₂, SrCO₃ and Sr (NO₃)₂), the ratio of water to TEOS and pH value on structure, morphology and purity of strontium silicate powders were investigated by X-ray diffractometer (XRD), scanning electron microscope (SEM) and differential scanning calorimetry-thermogravimetry (DSC-TG). At the same time, the mechanism for synthesis of Sr₂SiO₄ powder was also studied. The processing parameters of sol-gel process to produce Sr₂SiO₄ were optimized to be Sr (NO₃)₂ salt, the n (H₂O):n (TEOS):n (EtOH) as 24:1:5, pH value of 3-4 and calcining temperature of 800°C. Contrasted with traditional high-temperature solid-state reaction method, the sol-gel process reduced greatly the calcination temperature and the particle size, and also enhanced the purity of Sr₂SiO₄ powder.
