The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

Thermal expansion of FeWO4 (ferberite) and FeWO4:Fe2WO6 (7:1): a comparative X‐ray and neutron diffraction study

open access: yesJournal of Applied Crystallography, EarlyView.
Temperature‐dependent single‐crystal X‐ray, powder X‐ray and neutron diffraction measurements reveal the thermal expansion behavior of FeWO4 from 2 to 1123 K. Significant differences between natural ferberite and a FeWO4:Fe2WO6 composite highlight the influence of multiphase and microstructural effects on derived thermoelastic parameters.The thermal ...

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

open access: yesActa Crystallographica Section B, EarlyView.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...
