FIELD : chemical industry.
SUBSTANCE : invention refers to powdered zirconium oxide, way of its production and its application in fuel cells, notably for production of electrolyte substances for ceramic fuel cells. The powdered zirconium oxide containing up to 10 mole % of at least one metal oxide from the scandium, yttrium groups, the group of rare-earth elements and/or their mixtures is characterized by the extension density from 1.2 to 2.5 g/cm³ measured according to ASTM B 417.
EFFECT : powdered zirconium oxide characterized by a high electrical conductance and a high mechanical strength after agglomerating up to gas-impermeable bodies, and an efficient way of its production.
