COMPOSITE STRUCTURE AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To obtain a transparent composite structure which consists of a brittle material, has low visible ray transmissivity and is integrated with a base material. SOLUTION: Aluminum oxide fine particles having a submicron particle size and purity of 99.8% are filled into an aerosol generator 13. After that, a gas cylinder 11 is opened, and gaseous helium is introduced into the aerosol generator 13 through a carrier tube 12 at a flow rate of 3 liter/min to generate an aerosol in which aluminum oxide fine particles are dispersed into the gas. The aerosol is further carried to the direction of a structure formation chamber 14 through the carrier tube 12, and, the aluminum oxide fine particles are jetted toward a substrate 16 from a nozzle 15 while accelerating the same to a high speed.
