Tallentire, S.E. and Child, F. and Fall, I. and Vella-Zarb, L. and Evans, I.R. and Tucker, M.G . and Keen, D.A. and Wilson, C. and Evans, J.S.O. (2013) 'Systematic and controllable negative, zero, and positive thermal expansion in cubic Zr1–xSnxMo2O8.', Journal of the American Chemical Society., 135 (34). pp. 12849-12856.
We describe the synthesis and characterization of a family of materials, Zr1–xSnxMo2O8 (0 < x < 1), whose isotropic thermal expansion coefficient can be systematically varied from negative to zero to positive values. These materials allow tunable expansion in a single phase as opposed to using a composite system. Linear thermal expansion coefficients, αl, ranging from −7.9(2) × 10–6 to +5.9(2) × 10–6 K–1 (12–500 K) can be achieved across the series; contraction and expansion limits are of the same order of magnitude as the expansion of typical ceramics. We also report the various structures and thermal expansion of “cubic” SnMo2O8, and we use time- and temperature-dependent diffraction studies to describe a series of phase transitions between different ordered and disordered states of this material.
