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.
