WebApr 1, 1999 · These small diameter fibers (12 μm) have a chemical composition of 70% Al 2 O 3, 28% SiO 2 and 2% B 2 O 3 and are weavable. A dipping procedure was used to … WebMay 1, 2000 · An extremely simple processing route has been used to produce LaPO 4 (La-monazite)/alumina continuous fiber-reinforced ceramic composites. In this paper, the processing, microstructure and tensile properties are reviewed. In particular, the damage tolerance and notch insensitivity of this system, which contains monazite-coated fibers, …
Glass formation and crystallization in the alumina-silica
WebThe formation, structure, and dynamics of glasses in the alumina-silica-lanthanum phosphate system and their crystallization were investigated as a function of composition. These are of interest because of their potential as precursors for synthesizing ceramic-matrix-composites via co-crystallization of lanthanum monazite and either mullite or … WebJun 28, 2024 · Composites of (1 – x)LaPO 4 –xAl 2 O 3 (x = 0–1.0) were prepared in using LaPO 4 (monazite-type) powder obtained by mechanochemical activation of LaPO 4 ·0.5H 2 O (rhabdophane-type) powder for 10 days and commercial Al 2 O 3 alumina powder. Corresponding mixtures were pressed into tablets, calcined at 500°C for 1 h and then … hosting rhymes
