Abstract
A direct and simultaneous method to determine the <TEX>$SiO_2$</TEX> and <TEX>$ZrO_2$</TEX> in zircon sand of raw mineral and its treated one were studied by optical emission spectrometer using DC arc source. The synthetic standard was prepared by mixing with pure metal oxide, and it was diluted with buffer(graphite) and flux(<TEX>$Li_2B_4O_7$</TEX>). The mixing ratio of buffer and flux and its dilution ratio to sample was investigated in order to choose the best excitation conditions. The optimum mixing and dilution ratios were 0.22:1 and 40, and the standard deviations of analytical results were 1.9% for <TEX>$SiO_2$</TEX> and 4.7% for <TEX>$ZrO_2$</TEX>.
