The subject of researches is scientific grounded recommendations of the materials choice, modes of start and work of electroarc plasma generator for providing of their resource at the level of thousands hours of continuous running. During the implementation of the first stage of work the possibilities manufacturing of plasma generators emitters with the blowout of plasma to the atmosphere. The research examines new emission materials on the basis of difficult oxides of barium. The chemical compounds of the type BahMeuMezOv were examined as emission materials. During the accomplishment of the first stage the modes of activating of emitters were defined; the dependences of work functions on blending ratios were also defined. The first stage of the research also included the definition of dependences of work functions on the temperatures (up to 1800 K). The band semiconductors theory use for descriptionof the BahMeuMezOv materials thermoemission mechanism was validated; the dependence of work functions for the considered materials on partial pressure of active gases up to 10e-2 Pa was examined; the qualitative analysis of materials emission mechanisms was performed by the electronic microscopy methods.
