Abstract
Achieving an excellent corrosion resistance against calcium-magnesium aluminosilicate (CMAS) molten salt in multi-principal element monosilicates ((nRExi)2SiO5) presents a critical challenge. Herein, a non-equimolar rare earth elements (REEs) design approach was proposed, and ten variants of (nRExi)2SiO5 with three to five components were synthesized to investigate their CMAS corrosion resistance. The findings indicate that corrosion resistance is substantially influenced by the ionic radii of REEs, impacting corrosion behaviors from both thermodynamic and kinetic points of view. On the basis of these insights, a methodology for designing non-equimolar (nRExi)2SiO5 materials with enhanced resistance to CMAS corrosion at temperatures up to 1500°C is proposed.
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.
