Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Nanocomposite permanent magnets with reduced rare‐earth content represent a promising class of materials for next‐generation high‐performance applications. However, asynchronous precipitation of soft and hard magnetic phases often results in grain size mismatch and limited coercivity.

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).

Zhongguo shiyan zhenduanxue, 2012 目前已证实植物性食品中含有一定浓度的稀土元素,随着稀土微肥的广泛应用,稀土元素可经食物链进入机体内[1-4]。近年来有些学者报道了较低剂量的稀土化合物经口服,腹腔注射及尾静脉注射可使血清中生长激素及胰岛素水平显著升高[5-9],本实验依据这一点探讨口服三氯化钐对糖尿病大鼠胃粘膜的影响,为稀土元素应用于临床以及预防保健提供理论依据。

Optimized Copper Distribution and Enhanced Coercivity in PrO2‐Doped Sm2Co17‐Type Magnets
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A rational design of Cu distribution is crucial for achieving optimal magnetic properties in Sm2Co17‐type magnets. In this study, nanostructured PrO2 powders were employed to induce Cu redistribution at grain boundaries while preserving the cellular microstructure. The corresponding coercivity (Hcj), remanence (Br), and maximum energy product (

Dianci bileiqi, 2010 在不同温度下测量了稀土氧化物Gd2O3、Ce2O3掺杂ZnO-Bi2O3系压敏陶瓷的介电频谱,发现稀土氧化物的掺杂引起介电损耗显著增大。通过理论计算发现稀土氧化物掺杂后锌填隙和氧空位浓度显著增大,而耗尽层宽度明显减小。因此认为稀土氧化物引起施主性本征缺陷浓度的增大,导致Schottky势垒变薄,从而引起泄露电流的增大及非线性指数的下降。

基于实地和遥感调查的离子型轻稀土尾砂土壤侵蚀对植被修复措施响应
Shuitu Baochi Xuebao, 2020 稀土开采产生大量尾砂，导致严重土壤侵蚀，伴生水质和地质灾害，评价植被修复措施对稀土尾砂土壤侵蚀治理效果可为措施优选提供理论依据。以寻乌县离子型轻稀土尾砂区为研究区，基于1982—2015年GIMMS NDVI 3 g、DEM等遥感和尾砂理化性状现场调查数据，采用空间代时间方法，结合RUSLE模型及其全微分公式探究不同修复年限土壤侵蚀量对植被修复措施的响应机理。结果表明：1982—2015年研究区土壤侵蚀模数显著下降，倾向率为-60 t/（km2·10a），突变年份为2008年；在植被修复措施实施年 ...
