Abstract:
Plate-like gadolinium oxalate (Gd2(C2O4)3) with nano-scale was synthesized in a reverse microemulsion system, formed by Tween—60, hexanoic acid, n-octane and Gd(NO3)3 aqueous solution(K2C2O4 aqueous solution), by association with solvothermal method. The effects of the molar ratio of water to the Tween—60, the concentration of Gd(NO3)3 and reaction temperature on the morphology and the size of Gd2(C2O4)3 were studied. The morphology and size of Gd2(C2O4)3 were characterized by XRD and TEM, respectively. The experimental results showed that the size of the plate-like of Gd2(C2O4)3 increased with the increase in the molar ratio of water and the temperature, howerer, the size of Gd2(C2O4)3 decreased with the increase of the concentration of Gd(NO3)3.
