ABSTRACT:
In the novel method, before an electron-gun mount assembly is sealed into the neck of a CRT, at least the high-voltage electrodes and the adjacent portions of the focus electrodes are dipped into an aqueous solution consisting essentially of hydrogen peroxide and water. The solution contains substantially more than 10, and preferably about 30 to 50, weight percent of hydrogen peroxide.
