    摘要: The present invention is directed to SiC whisker and/or fiber reinforced glass-ceramic matrix composite articles wherein an alkaline earth aluminosilicate constitutes the predominant crystal phase. More particularly the composite articles will consist essentially of 10-60% by weight SiC whiskers and/or 15-70% by volume ceramic fibers and the glass-ceramic matrix will consist essentially, by weight on the oxide basis, of______________________________________ CaO 0-25 MgO 0-15 SrO 0-30 Na.sub.2 O 0-4 CaO + SrO 10-30 K.sub.2 O 0-6 Al.sub.2 O.sub.3 25-38 TiO.sub.2 0-12 SiO.sub.2 35-60 ZrO.sub.2 0-15 BaO 0-25 As.sub.2 O.sub.3 0-3 BaO + MgO + Na.sub.2 O + K.sub.2 O + TiO.sub.2 ZrO.sub.2 + As.sub.2 O.sub.3 0-30 ______________________________________ The preferred predominant crystal phase is selected from the group of anorthite and its pseudo-binaries, with mullite, cordierite, barium osumilite, and albite solid solution.
