ABSTRACT

ZnO was synthesized according to the transformation behavior and crystallization conditions of Zn-intermediate obtained by zinc sulfate as a precursor and NaOH, Na2CO3 as a alkali agents. For ZnO crystallization, Zn4(OH)6SO4·H2O andZn5(OH)6(CO3)2·H2O as a Zn-intermediate were calcined at 400°C and 800°C for 1 h, respectively, based on decomposition temperature from TGA. Zn4(OH)6SO4·H2O was confirmed to have mixed Zn4(OH)6SO4·H2O and ZnO at 400°C, and was completely thermally decomposed at 800°C to form ZnO phase. The prepared Zn5(OH)6(CO3)2·H2O as a Zn-intermediate by the reaction with Na2CO3 was transformed to a complete ZnO crystallization over 400°C. Nano-sized ZnO can be synthesized at a relatively lower calcination temperature through the reaction with Na2CO3.
