怎么发传真摘要：Silicon-aluminum-mixed oxide powder in the form of aggregated primary particles, exhibits (a) a weight ratio of aluminum oxide to silicon dioxide in total primary particles is 0.003-0.05; (b) the weight ratio of surface area of aluminum oxide to silicon dioxide of the primary particles in a subsurface layer with a thickness of approximately 5 nm of less than in the total primary particle and (c) a Brunauer-Emmett-Teller surface area of 50-250 m 2>/g. An independent claim is also included for producing the silicon-aluminum-mixed oxide powder, comprising (i) producing a vapor comprising at least one silicon compound comprising methyltrichlorosilane dimethyldichlorosilane, trimethylsilyl chloride and n-propyl trichlorosilane and transferring the vapor of a hydrolyzable and/or oxidizable aluminum compound parately or together by means of a carrier gas into a mixing chamber, where the weight ratio of the aluminum compound to silicon compound is 0.003-0.05, (ii) parately transferring at least a fuel gas and air into the mixing chamber, (iii) igniting the mixture of the vapor of the silicon- and aluminum compounds, fuel gas and air in a burner and burning the flame in a reac
tion chamber, and (iv) parating the solids from the gaous substances and treating the solids with water
vapor.
