This paper presents an analytical method for the determination of minor metals in white cast iron fused buttons. This method enables the measurement of metals in cast iron with rapidity and excellent analytical results. Buttons of 40 g appear to be ideal but smaller button samples can be tolerated. The fused buttons have good homogeneity, very slight weight loss, and no significant change in composition. Metal cast spectrochemical samples are analyzed in an inert atmosphere utilizing a high voltage spark.
