The present space program has necessitated extensive research with regard to high tem¬perature materials. Metallic silicides represent Just one of numerous types of compounds currently undergoing intensive study within the Materials Laboratory relating to this par¬ticular phase of materials development.nThis analytical study was initiated and conducted in support of in-house research per¬taining to the development of tungsten silicide and has resulted in a simple method for the determination of free tungsten. The various conditions stipulated by the procedure, as well as the recovery of tungsten from spiked silicide samples, were studied and reported upon in this report.
