Abstract

Two types of ceramic processes using ultrasonication are reviewed. One is called "sonochemical processing" in which physico-chemical phenomena such as reaction, precipitation, nucleation & growth, dispersion & agglomeration ... etc. are stimulated in the solution driven by a strong ultrasound. In the paper, syntheses of magnetite particles, spherical silica, and titania particles are reviewed. The other is to use very weak ultrasound with high frequency and small amplitude. It is suggested that weak ultrasonication efficiently enhances the homogeneity of a transparent solution used as a starting solution for precipitation of oxalate. Experimental data show that the precipitation behavior is significantly influenced by the solution structure.
