Supercritical equipment is one kind of high pressure vessel autoclave equipment, like industrial autoclave, to achieve excellent production process using supercritical state when the pressure (P) and temperature (T) of a fluid exceed the critical pressure (Pc) and critical temperature (Tc). It mainly includes supercritical foaming equipment and supercritical ceramic particle equipment which are all adopt supercritical technology to achieve the shape design and development of a certain substance in supercritical state.
