| Abstract: Polymorphic calcium zincate has been successfully synthesized in alkaline solution at various concentrations as well as at different temperatures. SEM images indicated that the concentration of the alkaline solution affected significantly the morphology of the calcium zincate crystal. Calcium zincate crystalline changed from regular parallelogram to unregular small crashed grains at a higher alkali concentration. And hexagonal calcium zincate crystal was obtained at higher reaction temperature. The stoichiometric composition for calcium zincate was Ca(OH)2·2Zn(OH)2·(2n-2)H2O as analyzed by TG, where n decreased with the increase of the alkaline concentration. XRD analysis showed that the temperature affected differently the growth of each face of the crystal, which led to the hexagonal shape of calcium zincate crystal. |
