摘要

A model was developed to study the process of current-ingited combustion synthesis. In this process, Joule heating raises the temperature to the ignition point, at which the Sample reacts to form a product. Two material systems were modeled: the synthesis of SiC and MoSi_2. It was found that the mode of combustion is a function of the size (radius) of the sample. The anticipated volume combustion mode was only evident in small samples. At higher values of the radius, the mode becomes wavelike (self- propagating high-temperature synthesis) in nature. The transition from volume to wave combustion mode also depended on the properties of the material. The results are interpreted in terms of thermal conductivity and heat-transfer conditions.
