A possibility has been established to obtain gradient functional
materials by sintering products of aqueous salt solution thermolysis.
Gas-impermeable electrolyte layers of stabilized cubic zirconium dioxide
have been produced by thermolysed particles onto metal and ceramic
substrates. The thermolysis pre-history has been shown to provide
phase and temperature uniformity of the deposited particles, short
solid-phase synthesis duration (~1 ms) of stabilized cubic zirconium
dioxide and sintering of materials in contact due to effective volume
diffusion at the particle and substrate temperatures in the range
of 1900-2100 K. The possibility to use the method in producing
solid oxide electrolytes for fuel cells is discussed.
