Polycrystalline Ni2SiO4 was exposed to a gradient in oxygen potential at 1336°C to cause kinetic decomposition into its component oxides, NiO and SO2. At the higher‐oxygen‐potential side NiO formed, and at the lower‐oxygen‐potential side SiO2 formed. This spatial distribution of SiO2 and NiO is consistent with diffusion data for silicate olivines which indicate that Ni diffuses much faster than either Si or O.
