Molybdenum disilicide and its composites have been fabricated by a number of researchers in recent years through vacuum plasma spray (VPS) forming. VPS is capable of producing dense, fine grained deposits of these high temperature intermetallics and is a promising technique for near-net-shape manufacturing. Reviewed here is VPS forming of high temperature silicide intermetallics, principally Mosi2 and its composites. A discussion will be given of the processing-structure-properties relationship of the spray formed silicide.
