FIELD: chemistry.
SUBSTANCE: solid electrolyte based on hafnium oxide contains hafnium oxide with oxide additives and is characterised by that the electrolyte contains hafnium oxide with scandium and yttrium oxide additives, and has the formula (1-x-y) HfO2+xSc2O3+yY2O3, where 0.07≤x≤0.1 and 0.01≤y≤0.04.
EFFECT: obtaining a solid electrolyte based on HfO2, having a stable structure and electroconductivity, which matches or surpasses electroconductivity of the best analogue.
