Abstract: A method of bonding multiple layers is provided. The method includes the steps of stacking the multiple layers on top of each other and volumetrically heating the stack of multiple layers to a predetermined temperature. It is preferred that the stack is heated by electromagnetic induction.

Abstract: Oxide-coated whiskers suitable for consolidation into or incorporation within a whisker-reinforced composite ceramic article are provided by dispersing inorganic whiskers in a colloidal oxide sol, separating the dispersion into fine droplets, and drying the droplets to provide a solid particulate product comprising the coated whiskers. The continuous oxide coating on the whiskers provides protection and aids in composite consolidation.

Abstract: There is disclosed a laminated ceramic structure including a facing member and a backing member, the two members being bonded together either directly or through an intermediate layer, the facing member being formed from a very hard ceramic such as a carbide having a KHN.sub.100 value in excess of 1000 kg/mm.sup.2, the backing member being a glass or glass-ceramic matrix having an enhanced capability or absorbing impact energy, preferably being fiber reinforced and having an energy absorbing capacity in excess of 10 KJ/m.sup.2.

Abstract: 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.
