AbstractMaterials with negative coefficients of thermal expansion (CTEs) can be used to prepare composites with specific CTE values. Negative thermal expansion behavior can be primarily attributed to two types of mechanisms: phase transition- and framework-type mechanisms. This paper reports Zr2SP2O12, which has unique negative thermal expansion behavior involving both mechanisms. Zr2SP2O12 undergoes a framework-type mechanism at temperatures <393 K or >453 K and an isosymmetric phase transition at 393–453 K. The volumetric CTE of α-Zr2SP2O12 is ~−70 p.p.m./K during the isosymmetric phase transition, and this value can be decreased by decreasing the proportion of sulfur. The minimum volumetric CTE of α-Zr2S0.9P2O12-δ is ~−108 p.p.m./K in the temperature range of 393–453 K. Between 303 and 773 K, the volume of α-Zr2S0.9P2O12 − δ is reduced by ~1.3%. Finally, this paper presents methods for the hydrothermal synthesis of α-Zr2SP2O12 and for controlling the sulfur content.
