我国贮量极丰富的氟碳铈矿,其稀土组份为铈组稀土。国内稀土应用的研究,大都以铈组稀土为添加剂,已成功地应用于钢、铁、高合金钢、有色金属合金以及毛皮、地毯、塑料、醇酸清漆等方面。铈组稀土总量直接测定方法的研究,对及时配合我国稀土资源的综合利用,具有积极的现实意义。 China’s extremely rich reserves of bastnaesite, rare earth components for the rare earth cerium group. The research of rare earth application in China mostly uses rare earths of cerium as additives, and has been successfully applied in the fields of steel, iron, high alloy steel, non-ferrous metal alloy and fur, carpet, plastic and alkyd varnish. The study on the direct determination of total rare earths in cerium group has positive and practical significance for the timely coordination with the comprehensive utilization of rare earth resources in our country.
