In summary, Zn-Sn-O compound powders were successfully synthesized by co-precipitation processs. The XRD
result disclosed that,without Sn loading, as-precipitated powder has a pure hexagonal wurtzite structure of ZnO. The
mixed phase of ZnO and ZnSn(OH)6 can be initiated after Sn loading over 30 at.% and has bare phase of
ZnSn(OH)6 when Sn loading over 40 at.%. It was further notified that the Sn loading has significant influence on
morphological properties and phase transformation of the as-precipitated powders.
