Silicate and oxide matrix CMCs are being developed for application in advanced gas turbines. High-performance Silicate/Nicalon CMCs have been characterised mainly as materials for interface, process and mechanical modelling due to their limited thermal and oxidative stability. Saphikon (Al{sub 2}O{sub 3}) monofilaments have been used in the development of interphase chemistry and processing via vapour and liquid-precursor methods. Prototype Al{sub 2}O{sub 3}-matrix CMCs have been fabricated and exploration of alternative fibre/interphase chemistries conducted via reactivity studies up to 1600{degrees}C.
