PRE-FORMED CONTROLLED PARTICLES FORMED OF FINE PARTICLES NON-CHEMICALLY BONDED TOGETHER, PRE-FORMED CONTROLLED PARTICLES FOR USE IN AN AEROSOL DEPOSITION METHOD, AND COMPOSITE STRUCTURE FORMATION SYSTEM INVOLVING CONTROLLED PARTICLES

摘要

A plurality of pre-formed controlled particles for use in an aerosol deposition method by which an aerosol with brittle material fine particles dispersed in a gas is sprayed toward a substrate to form a structure made of the brittle material fine particles. Each of the controlled particles includes an assembly packed with a plurality of fine particles which are not chemically bonded together, which include the brittle material fine particles, and have a mean primary particle diameter of 0.1 μm or more and 5 μm or less. The controlled particles have a mean circle-equivalent diameter of 20 μm or more.
