近日,由钨与稀土国检中心牵头起草的《钬铁合金化学分析方法稀土总量的测定重量法》与《钬铁合金化学分析方法稀土杂质含量的测定电感耦合等离子体原子发射光谱法》等两项稀土行业标准正式实施,填补了我国稀土合金产品中稀土总量和稀土杂质检测的空白。此前,国内外对钬铁合金中稀土总量和稀土杂质的检 Recently, Tungsten and Rare Earth National Inspection Center led the drafting of “holmium iron alloy chemical analysis of rare earth total weight determination method” and “holmium iron alloy chemical analysis of rare earth impurities content determination of inductively coupled plasma atomic emission spectrometry” two Rare earth industry standards formally implemented, to fill the rare earth alloy products in China total rare earth and rare earth impurities testing blank. Previously, at home and abroad on the holmium iron alloy rare earth total and rare earth impurities seized
