Synthesis and thermal properties of zirconium ortho- and diphosphates

Single phase sodium zirconium orthophosphates [NaZr2(PO4)3 and Na2Zr(PO4)2] and zirconium diphosphate (ZrP2O7) have been synthesized. The measured linear expansion coefficient of NaZr2(PO4)3 was rather small only reaching a value of 0.16% at 800 °C. The expansion coefficients of Na2Zr(PO4)2 and ZrP2O7 were also rather small and were 1.4 and 1.0% respectively at 800 °C. These phosphates showed different behaviour depending on the type of thermal pretreatment before the measurement of the expansion coefficient.
