FIELD: electrical engineering. ^ SUBSTANCE: electrode material comprises zirconium dioxide, metal oxide selected from the group containing calcium oxide, magnesium oxide, oxides of rare-earth metals and mix thereof, and additive of metal oxide comprising mix of oxides of bi- and tetra-valent uranium with formulation UO2-x, where x=0.20.4 with the following ratio of ingredients: mix of uranium oxides - 0.2Ç2.0 wt %, zirconium dioxide - 2Ç10 wt %, metal oxide making the rest. Method of producing said electrode material from initial components comprising compounds of cobalt, zirconium and metal selected from the following group: calcium, magnesium, rare-earth metals or mix thereof. Said method includes roasting and grounding of powder, powder sintering. Additionally, it comprises preliminary sintering of material at 900 to 1250C in neutral or oxidative atmosphere. Then follows grinding of produced material and adding thereto of uranium oxides mix and another sintering at 1100 to 1550C. ^ EFFECT: higher electric conductivity and electrochemical activity of electrode material. ^ 3 cl, 4 ex |
