【摘要】 本文提出用ＰＷ１４０４型Ｘ－射线荧光光谱仪快速测定钨精矿ＷＯ３（％）主量成分。用Ｌｉ２Ｂ２Ｏ７和Ｎａ２Ｂ２Ｏ７混合溶剂，把钨精矿粉样和纯ＷＯ３作高倍稀释熔融制成玻璃片，按ＷＬα分析线测定其强度值，并换算成相对强度即得出ＷＯ３（％）。更多还原

【Abstract】 A method for the determination of the major elements in tungsten ore using X ray fluorescence spectrometer(PW 1 404)was proposed.Tungsten ore and pure WO 3 were fused,of which glass disc was made with the mixing flux of both Li 2B 2O 7 and Na 2B 2O 7.WO 3(%)was calculated by the relative intensity of the analytical line.Satisfactory analytical results were obtained.更多还原
