Abstract
Within Mo-Si powder mixtures exhibiting different Si amounts the silicide formation reactions were governed by Si mobility within Mo. The influence of different experimental parameters on the completeness of silicide forming reactions was observed in detail. With increasing Si amount the reaction temperatures as measured within DSC runs were more affected by Si particle size and milling-mixing times. The more Si was available the more pronounced exothermic behaviour was observed.
