According to Science and Technology Daily, researchers from the Institute of Metal Research, Chinese Academy of Sciences, have discovered a new refrigerant material called potassium hexafluorophosphate. It can achieve cooling effects across a wide temperature range from room temperature to near absolute zero, making it the only solid-state phase-change refrigerant material with a full temperature range.

Reportedly, researchers have observed the "full-temperature compression effect" in potassium hexafluorophosphate for the first time. Experiments have shown that by applying pressure, the material can achieve continuous cooling across a wide temperature range, from room temperature (approximately 25°C) to liquid nitrogen (-196°C), liquid hydrogen (-253°C), and even liquid helium (-269°C).

This discovery opens the door to the development of a new generation of efficient, environmentally friendly, all-solid-state refrigeration technology, potentially revolutionizing the design of refrigerators and other refrigeration equipment.
