| titleOfInvention | Cathode for cathode ray tube |
| abstract | PROBLEM TO BE SOLVED: To strictly reduce the content of sulfur (S) of a rare earth metal oxide used for an electron emitting material layer 15 to a predetermined value or less, to maintain a high cathode current density and to stabilize for a long time. Provided is a cathode for a cathode ray tube which can achieve electron emission characteristics. SOLUTION: A cylindrical metal sleeve 13, nickel (N a cathode base 14 attached to one end of a cylindrical metal sleeve 13 and a composition in which a rare earth metal oxide is dispersed in an alkaline earth metal oxide containing barium (Ba); An electron emitting material layer 15 formed on the surface of the base 14; and the rare earth metal oxide has a sulfur (S) content of 100 ppm (corresponding to 0.01% by weight). The one desulfurized as follows is used. |
