Abstract

A mechanical route plays an important role in particulate coatings and synthesis. A type of particulate surface modification, i.e., oriented coating of fine particles onto the surface of a core particle, is proposed. For achieving this concept, the author has developed a two-step process involving mechanical and chemical methods. As an example, needle-like dicalcium phosphate fine particles were coated, in a standing-up state, onto the surface of nylon-12 core particles (avg 50um). The effect of the crystal structure of dicalcium phosphate on the particulate oriented coating was investigated.
