Glass panel for cathode ray tube, cathode ray tube employing this glass panel and method for producing cathode ray tube

A CRT in its entirety is to be rendered lightweight without detracting from the resistance against pressure of a panel or from characteristics desirable for the CRT. To this end, there is provided a glass panel for a CRT obtained on chemically reinforcing the glass containing 57 to 64 wt % of SiO2,...

Zusammenfassung:	A CRT in its entirety is to be rendered lightweight without detracting from the resistance against pressure of a panel or from characteristics desirable for the CRT. To this end, there is provided a glass panel for a CRT obtained on chemically reinforcing the glass containing 57 to 64 wt % of SiO2, 0.1 to 4 wt % of Al2O3, 5 to 10 wt % of Na2O, 5 to 10 wt % of K2O, 7 to 13 wt % of SrO, 7 to 11 wt % of BaO, 0.1 to 2 wt % of TiO2, 0.1 to 4 wt % of ZrO2 and 0.01 to 1 wt % of CeO2.
