Abstract

It is an interesting but challenge issue to prepare isotropic controllable thermal expansion materials with a wide coefficient of thermal expansion (CTE) range. Herein we report controllable thermal expansion in the double ReO3-type (Mn1-xNix)ZrF6 solid solutions, whose CTE varies from -4.4 to +15.5 × 10-6 K-1 (300-700 K). In particular, zero thermal expansion has been obtained in the composition of (Mn0.6Ni0.4)ZrF6. (Mn1-xNix)ZrF6 exhibits full solid solution character. The thermal expansion of (Mn1-xNix)ZrF6 is adjusted by the flexibility of the atomic linkages, which is confirmed by the technique of temperature-dependent high-energy synchrotron X-ray pair distribution function.
