What is a supercritical fluid?

Water, like any chemical substance, can exist in a gaseous, liquid or solid state… but that’s not all! When sufficiently heated and pressurized, it becomes a supercritical fluid, halfway between a liquid and a gas. Jacques Fages, a researcher in process engineering, biochemistry and biotechnology at IMT Mines Albi, answers our questions on these fluids […]
