Processing method of sintered electrodes for mercury vapour lamps was investigated. The results obtained were as follows:<BR>A mercury vapour lamp with sintered electrode exhibited a lower high frequency interference, a lower required ignition voltage and a longer life compared with that with spiral electrodes previously used.<BR>These effects are caused by the fact that a lower thermal conductivity and much greater amount of emitter materials are obtained in the sintered electrode compared with the characters involved in the spiral electrode.<BR>Because of the application of powder metallurgical method, sintered electrodes with good quality can be readily and economically manufactured.
