Abstract

A spectrochemical method for the determination of the major impurities, such as aluminum, iron, magnesium and silicon, in rutile single crystals and variously doped rutile is presented. By applying higher current (12 amp) and a 1:2 sample-to-graphite dilution by weight, the elaborate sample preparation needed for conventional fusion technique was avoided, and relatively higher detection limits were established. Average deviations are approximately ${\pm}8%$ for iron and magnesium in the concentration ranges of 0.007 to 0.7% and 0.006 to 0.6% respectively, and ${\pm}5%$ for aluminum and silicon in the range of 0.005 to 0.5%.
