The interactions of very pure and practically 100% dense α‐SiC with nickel and iron at 850°C were investigated. Large reaction zones, consisting of carbon and silicides of Ni and Fe, were examined by microprobe analysis. By means of marker experiments, the diffusion mechanisms were investigated: only Ni and Fe migrate through the reaction layer. Isothermal sections of the ternary phase diagrams Ni‐Si‐C and Fe‐Si‐C at 850°C are presented.
