Synthesis and Characterization of SrSiO₃ by Chemical Deposition Method

Abstract

Nitric acid strontium and potassium silicate as raw material, the strontium silicate was synthesized preparation the strontium silicate was synthesized by chemical deposition method， and the strontium silicate was sintered for three hours in 850 °C, 1000 °C and 1150 °C. The effect of sintering temperature on phase composition, microstructure and the influence of purity of strontium silicate was studied using X-ray diffraction and electron scanning electron microscope and differential thermal-hot heavy analyzer. The formation mechanism of strontium silicate by chemical deposition method was analyzed. The results show that: the sintering temperature is effect on phase composition and microstructure of the strontium silicate, Compared with traditional high temperature solid reaction process, the chemical deposition method could greatly reduce the sintering temperature, and improve the powder purity.

Research of Strontium Silicate Modified Zinc Oxide Thermal Control Coatings

“…The aqueous solution of potassium silicate (industrial grade, modulus (3.3) )and Zinc oxide were purchased from local market and used as received. The synthesis process of strontium silicate used in this paper, was according to that reported by Zhengquan Zhang [11],The characteristics of raw materials is listed in Table 1.…”
