PROBLEM TO BE SOLVED: To provide a mixed silicon-aluminum oxide powder, produced by a new flame hydrolysis method. SOLUTION: The mixed silicon-aluminum oxide powder, having a composition comprising 1-99.999 mass% Al<SB>2</SB>O<SB>3</SB>and the balance SiO<SB>2</SB>and produced by flame hydrolysis, has an amorphous structure (as shown by x-ray diffraction pattern), consists of co-grown primary particles containing crystallite of 1-200 nm size, and has a specific surface area of 5-300 m<SP>2</SP>/g. A method for producing the mixed silicon-aluminum oxide powder and the use of the mixed silicon-aluminum oxide powder are also provided. COPYRIGHT: (C)2009,JPO&INPIT
