Title: Production of glass substrate for information recording medium and information recording medium
Inventor: NIIKUMA YOSHIKANE
IPC: C03C23/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To largely suppress elution of alkali to a high quality level to use the glass for an information recording medium such as a magnetic disk by bringing a glass substrate containing alkali ions for an information recording medium into contact with a molten salt of pyrosulfates and/or hydrogen sulfates. SOLUTION: The glass substrate for an information recording medium is treated by dipping the glass substrate containing alkali ions in a molten pyrosulfates or hydrogen sulfates or bringing one surface of the substrate into contact with the molten salt. The temp. of the molten salt is 275 to 300 deg.C or higher to decrease the elution of alkali to zero or almost zero. The upper limit of the temp. is 350 to 400 deg.C so as to prevent blueing of the glass substrate. For a chemically reinforced glass, the upper limit is preferably 300 to 350 deg.C so as to prevent decrease in the strength. The effect to suppress elution of alkali can be obtd. only by treating with a molten salt for >=5 min. As for the glass substrate, an aluminosilicate glass, silicate glass having high-valence metal ions, soda lime glass or its chemically reinforced glass can be used.
