ガラスの製造方法
Document Type and Number:
Japanese Patent JP5725734
Kind Code:
B2
Abstract:
Provided is a method of producing porous glass having pores with a uniform pore diameter entirely, particularly in the case of phase-separated glass, including selectively removing a denatured layer formed on the surface of glass easily. The method of producing glass includes: forming phase-separated glass containing silicon oxide, boron oxide, and an alkali metal oxide; bringing an alkaline solution held by a porous supporting member into contact with the denatured layer formed on the surface of the phase-separated glass to remove the denatured layer; and immersing the phase-separated glass with the denatured layer removed therefrom in an acid solution to form pores in the phase-separated glass.
