必要となり、コストが高くなったり、また生産性に問題
があった。[Problems to be Solved by the Invention] The CRT glass panel requires a special kiln to melt glass of a specific composition, and requires polishing after press molding, which increases costs and reduces production. There was a problem with sexuality.

れる。The above panel is made by molding a soda lime silica glass plate into a desired shape such as a CRT.
The panel is immersed in a molten salt containing at least one of potassium ions, rubidium ions, and cesium ions and lithium ions at ℃ for 0 to 1 hour to convert the sodium ions on the surface of the panel into potassium ions, rubidium ions, and lithium ions.
It can be obtained by replacing at least one type of cesium ion with lithium ion in a single ion exchange.

圧縮層が生じるため、ガラス強度が向上する。In the mtJ panel, some of the sodium ions on the glass surface are replaced with at least one of potassium ions, rubidium ions, and cesium ions and lithium ions, so the mixed alkali effect prevents browning even when irradiated with electron beams. Since a compressed layer is formed on the surface of the glass, the strength of the glass is improved.

るとブラウニングが生じ易い。The glass surface to which the electron beam is irradiated is preferably the surface opposite to the surface that contacts the molten tin of the float bath. If the glass surface is in contact with a 10-ton bath of molten tin, the ion exchange speed will be slow and the ion exchange treatment time will be unnecessarily long. Further, if Sn is present on the glass surface, browning is likely to occur.

生ずる。In the glass panel, lithium ions substituted with sodium ions exist as lithium oxide, and the average weight % of the lithium oxide is 0 at least in a depth of 10 μm from the glass surface where the electron beam is irradiated. ..
It is preferably 1 to 3%. When the average weight percent of the lithium oxide exceeds 3%, the glass strength decreases, and if too much of the lithium oxide is used, the glass surface becomes cloudy and minute racks are formed.

浸入深さは55m乃至20μmであるのが好ましい。In a molten salt containing at least one of potassium ions, rubidium ions, and cesium ions and lithium ions, the mol% of lithium ions relative to the cations of at least one of potassium ions, rubidium ions, and cesium ions excluding lithium ions is o,
0.4 to oa! % is preferable. When the mol% of lithium ions exceeds 0.17%, the glass strength decreases as described above, and in extreme cases, the glass surface becomes cloudy and minute racks are formed. Further, the penetration depth of the substituted potassium, rubidium, and cesium into the glass panel is preferably 55 m to 20 μm.
