description: The purpose of the work is liquidâphase synthesis and investigation of physicochemicalÂ properties of Gd2O3-SrOâCo2(Ni2)O3 nanopowders and ceramicsÂ based on them, with the prospect of their further use as cathodesÂ of solid oxide fuel cells. In the course of the work, highly dispersedÂ powders of the compositions Gd1âxSrxCo0,5O3âÎ´ (x = 0,1, 0,15, 0,2, 0, 25); Gd0.4Sr0,1Ni0,5O3;Â Gd0,125La0,125Sr0,25Co0,5O3Â were synthesized, using aÂ method of joint crystallization of salts, and studied. The specificÂ surface area is in range of values from 3.1 to 5.6 cm3/g,Â the average pore size is in range from 7 to 61 nm, and the specific pore volume is inÂ range from 0.019 to 0.036 cm2/g. Ceramic samples were created and studied on their basis. The average size of the crystallites was 55 nm (atÂ a temperature of annealing 1200â), the open porosity was 20%, the specificÂ electrical conductivity (at an ambient temperature of 700â) wasÂ 0.32 Â· 10-1 Cm/cm.Â As a result, it was concluded that ceramicÂ materials created on the basis of nanopowders of the systemÂ Gd2O3âSrOâCo2(Ni2)O3 can be used as cathodes of solid oxide fuel cells operating at mediumÂ temperatures (400-700â).
