Rare Earth Aluminophosphosilicate Glass Precursors for Ceramic-Matrix-Composites (REAPS CMC's)

Abstract

This project was dedicated to assessing the utility of rare earth aluminophosphosilicate (REAPS) glasses within the Al203-AlP04-LaP04-Si02 system as precursors for fabricating ceramic-matrixcomposites of (Al6Si2013) and monazite (LaP04). The specific objective was to investigate selected issues for devising strategies of low-temperature pathways of viscous sintering of glass powders and crystallization anneals to produce dense monolithic ceramics of very fine textures. The ultimate goal, beyond the scope of this work, will eventually lead to innovating low temperature synthesis routes for ceramic composites of high fracture toughness and high temperature applications.
