    摘要: A sealing method and sealed assemblies incorporating novel devitrifiable sealing frits based on thermally crystallizable alkaline earth aluminosilicate glasses, are disclosed. The frits exhibit improved compatibility with refractory composites employed for the fabrication of high temperature fiber-reinforced glass-ceramic assemblies and can be cured at temperatures below those needed to cure prior art sealing compositions to provide strong seals wherein refractory crystal phases selected from the group consisting of anorthite (CaO.Al.sub.2 O.sub.3.2SiO.sub.2), celsian (BaO.Al.sub.2 O.sub.3.2SiO.sub.2), and sanidine, orthoclase or other potash feldspar (K.sub.2 O.Al.sub.2 O.sub.3.6SiO.sub.2) polymorphs constitute the principal phases.

    摘要: There is disclosed a method of producing a slurry composed of ion-exchanged, synthetic mica crystals dispersed in a polar liquid. The method comprises providing a synthetic, lithium and/or sodium, water-swelling body of selected crystal type, and dispersing the mica body in the polar liquid while simultaneously effecting an exchange of larger cations from a contacting source with lithium and/or sodium ions from the mica crystals. The synthetic mica body may be vigorously mixed in a dilute solution of the exchangeable ion source. Alternatively, the mica body may be disintegrated in a mixer, the exchangeable ion source added to form a paste and more liquid added to dilute the paste.
