Abstract: A method for producing a silica composite particle including a silica particle and at least one compound in which an aluminum atom bonds to an organic group through oxygen. The method includes: (i) providing a silica particle dispersion liquid having a silica particle content of about 20 mass % or more; (ii) mixing and reacting a compound represented by formula (S1) and the silica particle dispersion liquid to obtain a slurry; (iii) providing the at least one compound; and (iv) then mixing and reacting the slurry with the at least one compound to form the silica composite particle.

Abstract: A silica-titania composite has a BET specific surface area, as determined by BET analysis of a water vapor adsorption isotherm, in the range of 250 m2/g to 500 m2/g and a contact angle with water of 100° or greater. In the water vapor adsorption isotherm, an adsorbed amount at relative pressure P/P0=0.1 is in a range of 65 cm3/g to 120 cm3/g, an adsorbed amount at relative pressure P/P0=0.5 is in a range of 150 cm3/g to 300 cm3/g, and an adsorbed amount at relative pressure P/P0=0.9 is in a range of 350 cm3/g to 500 cm3/g.
