Title:
PRODUCTION METHOD OF COMPOSITE PARTICLE
Document Type and Number:
Japanese Patent JP2004130296
Kind Code:
A
Abstract:
To provide the production method of composite particles by simplified processes causing little coagulation of the particles without using an organic solvent toxic to the human body nor heat treating, and to provide the composite particles by the production method.
In this production method of composite particles, particles are brought into contact with a substance having adsorbability to the surfaces of the particles in the presence of a supercritical fluid or a subcritical fluid, and after adsorption of the substance having adsorbability on the surfaces of the particles, the supercritical or subcritical fluid is eliminated, to produce the composite particles.
