    Zirconolite Matrices for the Immobilization of REE–Actinide Wastes by Sergey V. Yudintsev, Maximilian S. Nickolsky, Michael I. Ojovan, Olga I. Stefanovsky, Victor I. Malkovsky, Amina S. Ulanova, Lewis R. Blackburn

    Published 2023-07-01
    “…Detailed analysis of both natural and synthetic zirconolite-structured phases confirms that a selection of zirconolite polytype structures may be obtained, determined by the provenance, crystal chemistry, and/or synthesis route. The production of zirconolite ceramic and glass–ceramic composites at an industrial scale appears most feasible by cold pressing and sintering (CPS), pressure-assisted sintering techniques such as hot isostatic pressing (HIP), or a melt crystallization route. …”

    Selective Separation of Fluorite from Scheelite Using <i>N</i>-Decanoylsarcosine Sodium as a Novel Collector by Zekun Miao, Liming Tao, Jianjun Wang, Zheyi Jiang, Tao Peng, Wei Sun, Zhiyong Gao

    Published 2022-07-01
    “…The results of adsorption capacity detections, zeta potential tests, and FTIR analysis showed that the negatively charged SDAA prefers to adsorb onto the positively charged fluorite surface due to the electrostatic interaction. The results of crystal chemistry and DFT calculations showed that SDAA has a stronger chemical interaction and more electron transfer numbers to the Ca atom on the fluorite surface and forms a Ca-SDAA complex. …”
