Abstract
A dispersion method for uniformly dispersing solid or liquid fine particles in a solvent utilizes a supercritical fluid. A dispersoid of a solid, a liquid or the like is mixed with a solvent, and the resulting mixture is fed to a supercritical vessel. A supercritical solvent is then fed to the supercritical vessel and heated and compressed to a level higher than the critical temperature and critical pressure thereof to convert it to a supercritical fluid. The supercritical fluid and mixture of dispersoid and solvent are mixed together to form a supercritical mixture, which is released to atmospheric pressure in an explosion-crashing tank and subjected to collision within the explosion-crashing tank to efficiently disperse the dispersoid in the solvent.
