Synthesis of CdSiO3 powder by sol―gel method

Abstract Pure CdSiO 3 powder was successfully prepared by sol–gel method using Cd(NO 3 ) 2 ·4H 2 O and (CH 3 CH 2 O) 4 Si (TEOS) as raw materials. The prepared powders were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) respectively. The effects of the reacting temperature and the calcining time on phase formation and size homogeneity were investigated. The results indicated that the single phase CdSiO 3 powders with good homogeneity and good crystallization could be obtained by sol–gel method at 900 °C for 2 h.
