Brittle material fine particles, brittle material film manufacturing method and composite structure

摘要

PROBLEM TO BE SOLVED: To provide brittle material fine particles capable of forming a transparent and thick brittle material film on a resin base material without a base layer. To provide a method for producing a brittle material film using the brittle material fine particles. To provide a composite structure having a brittle material film by the production method. SOLUTION: The brittle material fine particles for forming a brittle material film on a substrate by an aerosol deposition method (AD method), which are a compound of a boron atom, a metal atom and an oxygen atom, and aluminum oxide and boron oxide. Brittle material fine particles (excluding glass) containing one or more selected from the group consisting of a mixture of. A method for producing a brittle material film, which comprises a step of applying the brittle material fine particles onto a substrate by an AD method to form a brittle material film. A composite structure having a brittle material film according to the method for producing the brittle material film on a base material. [Selection diagram] None
