摘要：

Ten elements (Co, Cr, Cu, Fe. Mn, Ni, Ti. V. Zn and Zr) in molybdenum disilicide are quantitatively coprecipitated with lanthanum hydroxide. Sample treatment and effects of acids, pH and La are studied. Traces of impurities are determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) using matrix-matched calibration solutions.
