COMPOSITE STRUCTURE AND METHOD AND APPARATUS FOR FORMING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a structure composed of≥2 kinds of brittle materials having a novel characteristic without being accompanied by a heating and firing process. SOLUTION: The structure is constituted so that crystals of≥2 kinds of the brittle materials such as ceramics or metalloids are dispersed, a part composed of the brittle material is polycrystalline, the crystal constituting the polycrystalline part has not crystal orientation and a grain boundary layer composed of a vitreous material does not exist practically in the boundary face among the crystals.
