Abstract

Zinc stannate (ZnSnO₃) and zinc stannate-coated nm-CaCO₃ (ZS-CaCO₃) were synthesised from precursors which for the latter were formed by a homogeneous precipitation method with ultrasonic and azeotropic technology. The calcined products of ZnSnO₃ and ZS–-CaCO₃ were characterised by XRD and TG/DTA. The results indicated the optimal temperature for calcining was at 500°C. The surface of nm-CaCO₃ was characterised by XPS and TEM, and the results showed that ZnSnO₃ had effectively coated the surface of nm-CaCO₃. The grain size of ZS-CaCO₃ was about 50–70 nm.
