Abstract

PURPOSE:To achieve the optimal decomposition schedule in a short term by employing the chemical analyzing method in the exhaust process of a fluorescent lamp. CONSTITUTION:In the process where the three component carbonate emitter of barium, clcium and strontium applied on a filament coil is electrically heated to convert into a three component oxide thus to provide the electron emission performance, the decomposition schedule is set such that the residual carbon per 1mg of the three component oxide is 20-40mug.
