METHOD OF PRODUCING PASTE FOR THIN-FILM SOLID ELECTROLYTE OF ELECTROCHEMICAL DEVICES Russian patent published in 2020 - IPC H01M8/126 

FIELD: technological processes.

SUBSTANCE: invention relates to production of paste for production of gas-tight layers of solid electrolytic materials having high ionic conductivity in oxygen, for microtubular solid oxide fuel elements (MT SOFE) of anode-bearing structure. Method of producing the paste involves mixing in an ultrasonic bath and grinding with ceramic balls to viscosity of 0.2 Poise in a bead mill mode of mixing a powder of cerium oxide doped with gadolinium Ce_0.9Gd_0.1O_1.95 (CGO), butylglycol, BYK-111 and polyvinyl butyral in ratio of 40/55/1/2 respectively. Method allows varying viscosity of paste depending on method of coating application and on required thickness of coating by changing ratio of solvent and solid phase of used oxide.

EFFECT: technical result is simpler technology and lower power consumption of making paste with possibility of controlling viscosity of end product.
