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.
