ABSTRACT:
Panel glass, for a cathode ray tube, which has an SrO/(SrO+BaO) ratio of from 0.35 to 0.70, an X-ray absorption coefficient of 36.0 cm−1or more at the wavelength of 0.6 angstrom, wherein Na2O/R2O, K2O/R2O and Li2O/R2O (R2O: Na2O+K2O+Li2O) molar ratios fall within a range surrounded by the points A (0, 0.2, 0.8), B (0.2, 0.2, 0.6), C (0.4, 0.6, 0), D (0.2, 0.8, 0) and E (0, 0.4, 0.6) in the ternary phase diagram as shown in FIG.1.
