摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing SiO2-TiO2glass with the low coefficient of expansion which has no defect of a conventional technology. SOLUTION: A dispersion liquid the contains the silicon - titanium mixed oxide powder manufactured with the flame-hydrolysis method with BET surface area of 5-500 m2/g comprising titanium dioxide of 0.5-20 mass% to the powder, water and at least one kind of pH regulators which can be completely removed from the reaction mixture when heating while the powder has a solid content of 40-80 mass% to the dispersion liquid.
