Abstract

Multi-phase glass-ceramic composites (i.e., composite materials containing multiple ceramic crystallites dispersed in a glass matrix) that have applications as potential nuclear waste form materials have been synthesized and examined. Crystallites of xenotime-type (YPO₄) phosphates and monazite-type (LaPO₄) phosphates were dispersed in borosilicate glass. The composition of the glass matrix was varied to eliminate the formation of unwanted secondary phases. Powder X-ray diffraction (XRD), X-ray absorption near-edge spectroscopy (XANES), Scanning Electron Microscopy (SEM), and Energy-Dispersive X-ray spectroscopy (EDX) were employed to investigate the long-range order, local chemical environment, and morphology of the composite materials. The XRD patterns and XANES spectra revealed the exclusive presence of LaPO₄ and YPO₄ phases within the composite subsequent to the modification of the glass matrix. The SEM images and EDX maps collected from these composite materials also showed only the presence of LaPO₄ and YPO₄ after modification of the glass composition by removing Na₂O and CaO.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
