《GB/T 2969-2008氧化钐》由TC229(全国稀土标准化技术委员会)归口,主管部门为国家发展和改革委员会。
本标准规定了氧化钐的要求、试验方法、检验规则与标志、包装、运输、贮存等。本标准适用于化学法制得的氧化钐,可供制作金属钐、磁性材料、电子元器件和陶瓷电容等用。 本标准是对GB/T2969―1994《氧化钐》的修订。本标准与GB/T2969―1994《氧化钐》相比,主要变化如下:
―――按GB/T17803―1999《稀土产品牌号表示方法》的要求采用数字牌号;
―――删除了纯度不小于96%的产品牌号;
―――增加了纯度不小于99.99%的产品牌号,该牌号除考核相邻稀土杂质外,对其他稀土杂质含量也进行了考核,其他稀土杂质考核采用“合量”;
―――增加了对非稀土杂质Al2O3 的考核指标;
―――调整了对非稀土杂质Fe2O3、SiO2、CaO 及Cl- 的考核指标。
