A compacted mixture of heat-generating powders including about 1 to 20 weight percent of silicon results in improved heat transfer to unreacted components or to the ambient during condensed state exothermic reaction to form intermetallic products. Gettering of expanding gases from impurities and incomplete compaction is also provided by the silicon addition, thereby increasing overall heat conductivity of the compact and further improving the heat transfer rate from the reacted region. |
