Equation of state and phase transitions of the cubic NTE material Cd(CN)2

DOI

Despite being the material showing the largest isotropic NTE, Cd(CN)2 is remarkably little studied, particularly compared to isostructural Zn(CN)2 and the canonical NTE material ZrW2O8, as such this is an exciting opportunity to study this system using neutrons. This study aims to carry out a comprehensive and long-needed variable-p,T structural study of 112Cd(CN)2, with a number of important objectives: (i) to determine the nature of its structurally complex low-temperature phase(s) (T < 150 K); (ii) to determine the equation of state, including the ambient-temperature bulk modulus and the temperature-dependence of the bulk modulus; (iii) to identify and characterise structurally the high-pressure phase(s); and (iv) to exploit the resolution and d-spacing coverage offered by HRPD to characterise properly the p,T-dependent changes in Cd(CN)2.
