Particle size reduction using supercritical materials |
| abstract |
The present invention relates to a method of reducing particle size by the use of a supercritical gas, such as carbon dioxide or a refrigerant. The material is swollen by the supercritical gas at a high pressure. After the material has been allowed to swell under a high pressure, the pressure is rapidly dropped. When the external pressure is rapidly dropped, the material explodes as the supercritical gas absorbed into the material rapidly expands outward. |
