Abstract: PURPOSE: Provided is a method for mixing ceramic and natural fiber by using supercritical fluids which is characterized by being possible to expand practical use range of functional ceramic and to increase an effect of the ceramic, being possible to omit a separating process because the supercritical fluids are used and preventing environmental pollution. CONSTITUTION: The method is as follows: grinding ceramic into powder having under 1micron; putting the ground ceramic and the natural fiber into a high temperature and high pressure reaction chamber; and reacting for sufficient time under the condition of the supercritical fluids. The ceramic is yellow soil, elvan stone, tourmaline and so on. The supercritical fluids are carbon dioxide, air and nitrogen.
