Abstract

The single phase compound Ca_0.5Zr₂P₃O₁₂ (CZP) was prepared by solid state reaction technique. This material shows a negative thermal expansion in the temperature region of 30°-500°C. The effect of MgO and ZnO addition on the sintering behavior and thermal expansion characteristics of Ca_0.5Zr₂P₃O₁₂ was investigated. Mg₃(PO₄)₂ and Zn₃(PO₄)₂ were observed as minor phases responsible for improving the overall thermal expansion of CZP + MgO, ZnO systems. SEM studies and density data are also discussed. Observed sintering kinetics suggest that a liquid phase is promoting the sintering reaction. 98+% of theoretical density and near zero expansion behavior in certain compositions were observed.
