| Abstract: | The formation of a Cu–Ni solid solution supported on Y molecular sieve has been studied by measuring the changes in magnetization of the Cu–Ni/Y system heated in vacuum at 450°C. The aggregation of metal into crystals is comparatively fast in the first stage of sintering, while the homogenization of the solid solution by volume interdiffusion of the components constitutes the other, much slower stage.
