Abstract : Summarized herein are the findings from a two month trip to Japan from mid-September to mid-November 1991 to evaluate Japanese technology in oxynitride glasses and fibers and in carbide and nitride fibers and whiskers. The information discussed was obtained through visits to universities, companies, Government institutes, and through attendance at three conferences. It was learned that the development of a process for the production of oxynitride glass fibers is still being actively pursued and that, while high temperature instability problems are well-recognized, the production of carbide or nitride fibers with good high temperature stability is still several years away. Also discussed are new developments in several research areas including ceramic matrix composites, sol-gel technology, ceramic powder preparation, and high strength ceramics.
