Abstract

Phase formation in the BaF₂–NdF₃ and BaF₂–PrF₃ systems was studied by solid-phase annealing at 750°С and syntheses in molten NaNO₃ flux at 500°С. We observed the formation of Ba₁₋_хR_хF₂₊_х fluorite solid solutions in the aforementioned systems, and these solid solutions underwent ordering to form ordered Ba₄Nd₃F₁₇ and Ba₄Pr₃F₁₇ fluorite-like phases at 917°С and 880°С, respectively.

BaF2-NdF3和BaF2-PrF3体系的相图

采用750°С固相退火和500°С纳米熔剂合成的方法研究了BaF2-NdF3和BaF2-PrF3体系的相形成。我们观察到在上述体系中形成了Ba1−хRхF2+萤石固溶体，这些固溶体分别在917°С和880°С处有序地形成了Ba4Nd3F17和Ba4Pr3F17萤石样相。

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
