A supercritical fluid is any substance at a
temperature and pressure above its critical point. Normally the
pressure/temperature/volume phase diagram of a material shows different phases
in equilibrium such as solid liquid and gas phases. At the critical point there
is only one phase, a liquid-like phase with special properties. It can diffuse
through solids like a gas, and dissolve materials like a liquid. In addition,
close to the critical point, small changes in pressure or temperature result in
large changes in density, allowing many properties of a supercritical fluid to
be "fine-tuned". Supercritical fluids are suitable as a substitute for organic
solvents in a range of industrial and laboratory processes. Carbon dioxide and
water are the most commonly used supercritical fluids, being used for
decaffeination and power generation.
