Characteristics of tungsten cathode activated by rare earth metal oxide are described at first, which is widely used as hot cathode material of plasma torch. It is shown that behavior of rare earth metal oxide included in tungsten electrode has decisive effect on the properties, durability and consequently consumption, and is governed by temperature field inside the cathode. And some types of temperature fields with which the rare earth metal oxide could well behave. Essential factors for designing the long life plasma gun are discussed.
