The formation of a periodically layered structure in a AB/X ternary diffusion couple was described. According to the proposed model, the final AX and BX products were formed via 2 different reaction schemes; periodically switching from one to the other once the supersaturation required for the nucleation of the corresponding compound had been reached.
