Abstract

Determination for $Ta_2O_5$,$Nb_2O_5$ and $SnO_2$ in tin slags was investigated by X-ray spectrometric method. Standard addition-dilution method was attempted and showed a comparable accuracy with standard calibration curve method. Pure chemicals($Ta_2O_5$,$Nb_2O_5$ and $SnO_2$) were added to the samples and diluted with silica or ferric oxide. For the determination of $Ta_2O_5$and$SnO_2$ , silica was more suitable than ferric oxide while the latter was more preferable than the former for $Nb_2O_5$.
