Abstract
Methods of briquetting ferroalloy powder for fluorescent X-ray analysis were studied with special considerations on the relation of sample weight, crushing time and briquetting pressure with X-ray intensities. The analysis of variance suggested that crusing conditions were highly significant when the ferroalloys powdered under a fixed crushing condition were prepared into briquettes under pressure of 3040 tons, the X-ray intensities showed only little fluctuation and were highly reproducible. The X-ray intensities showed linear relationships with the results of chemical analysis.
