A one-step synthesis of rare-earth phosphate-borosilicate glass composites.

ABSTRACT: A new 1-step method for synthesizing glass-ceramic composites consisting of rare earth phosphates (REPO₄) dispersed in borosilicate glass (BG) is reported herein as an alternative to the 2-step approach that is traditionally used. The effect of annealing time and annealing temperature on the formation of the 1-step glass-ceramic composites was investigated. Backscattered electron images and energy dispersive X-ray maps were collected to observe the morphology and chemical distribution in the glass-ceramic composites. X-ray diffraction was used to study the long-range order and X-ray absorption near edge spectroscopy was used to study the local environment of La, Y, P and Si. All analyses showed glass-ceramic composites made by the 1 and 2-step methods were similar to each other
