Electrode coating composition and electrode for cold cathode gas discharge lamp

Claim 1

AN ELECTRODE COMPRISING A HOLLOW CYLINDRICAL METAL SHELL WHICH IS OPEN AT ONE END AND CARRYING AN ELECTRONEMISSIVE COATING ON THE LINEAR SURFACE THEREOF, SAID COATING HAVING BEEN PREPARED BY MIXING TOGETHER A FIRST LITHIUM COMPOUND WHICH DEOCMPOSES ON HEATING TO LITHIUM OXIDE, AND A SECOND LITHIUM COMPOUND WHICH DECOMPOSES ON HEATING TO LITHIUM METAL WHILE PRODUCING A NONOXIDIZING ATMOSPHERE, THE MOLAR RATIOS OF SAID FIRST LITHIUM COMPOUND AND SAID SECOND LITHIUM COMPOUND BEING FROM 1:1 TO 1:3, FORMING A SUSPENSION OF SAID MIXED LITHIUM COMPOUNDS BY MIXING SAME WITH A BINDER AND A SOLVENT, COATING SAID SUSPENSION ONTO THE INNER SURFACE OF SAID ELECTRODE SHELL, PLACING SAID COATING ELECTRODE SHELL M AN EVACUATED CONTAINER, HEATING SAID COATED ELECTRODE SHELL TO A TEMPERATURE OF FROM 800*C. TO 1000*C. TO DECOMPOSE SAID COATING, AND CONTINUING SAID HEATING UNTIL DEGASSING OF SAID COATING CEASES.
