Preparation of coated particles by an injection method was presented. The raw material of a coating layer is injected into a core particle suspension in which a precipitant is dissolved. By this method, some coated particles including titania hydrate-coated calcium carbonate powders and alumina hydrate-coated SiC whiskers were prepared. It was noticeable that CaCO_3, which is soluble in the raw material of titania hydrate, could be coated with titania hydrate. Furthermore, it was shown that aluminum nitrate and aluminum chloride as well as aluminum sulfate were useful as the raw material salts. Homogeneous nucleation and coalescence of the homogeneous nuclei onto the coating layers were expected to be included in the coating process.
