ULTRASONIC METHOD FOR DEPOSITION OF EMITTER TO ELECTRODES OF GAS-DISCHARGE LAMPS

摘要

A method for deposition of emitter to electrodes of gas-discharge lamps via vacuum consists in following: electrodes are immersed into emitter liquid suspension, thereafter it is removed; solvent is evaporated. Before and during immersion and holding electrodes in suspension, the last one is treated with ultrasound which is turned off prior to electrodes will be taken out of suspension.
