A pioneering research team from the Institute of Metal Research at the Chinese Academy of Sciences has, for the first time, identified the barocaloric effect across the full spectrum of temperatures in potassium hexafluorophosphate (KPF6), an inorganic plastic crystal material. This groundbreaking discovery enables KPF6 to function as a refrigeration material, effective from ambient temperatures down to extremely low temperatures of -269°C, when subjected to pressure. Consequently, KPF6 is currently the sole solid-state phase change refrigeration material capable of covering the entire temperature range.
