Document Type and Number:
WIPO Patent Application WO/2015/111726
Kind Code:
A1
Abstract:
Provided is a method capable of suppressing the corrosion of glass in contact with a liquid containing fluoride ions, or a condensate of gas vaporized therefrom, without needing to add an alkaline substance and without additional restrictions as to temperature, pH, fluoride ion concentration, water content, and the like. A method for suppressing the corrosion of glass in contact with a liquid containing fluoride ions and/or a condensate of a gas vaporized therefrom, wherein the liquid contains a powder containing silicon dioxide, the amount of silicon dioxide being one-fold or more by molar ratio with respect to the fluoride ions.
