摘要： Fiber-reinforced ceramic matrix composite articles are fabricated by combining inorganic reinforcing fibers with dispersions of powdered ceramic matrix materials in organic vehicles which are thermoplastic solids. The dispersions are solid at room temperature, and are melted and combined with the fibers as heated liquid dispersions. Following application to the fibers, the thermoplastic dispersions are solidified by simple cooling; no solvent removal or drying step is required.

摘要： A colored, transparent glass-ceramic having a beta-quartz solid solution as its primary crystal phase, and a method of producing the glass-ceramic. The glass-ceramic is produced from a Li.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 precursor glass containing an amount of TiO.sub.2 effective as a nucleating agent up to about 6%, and having a color package composed of 10-20 ppm Co.sub.3 O.sub.4, 550-650 ppm Fe.sub.2 O.sub.3, 19.5-20.5% Al.sub.2 O.sub.3 and 2.5-3.0% Li.sub.2 O.

摘要： A method of forming an activated carbon or graphite structure is provided by (1) forming, such as extrusion, of a plasticized mixture of: binder selected from cellulose ether and derivative thereof, starch, and mixture thereof; furfuryl alcohol and/or polyfurfuryl alcohol; and carbon, graphite, or a carbon-containing material; and (2) subjecting the formed mixture to a carbon-forming pyrolysis step. The use of furfuryl alcohol allows extrusion at ambient temperatures and provides a "reactive" solvent that provides carbon upon pyrolysis.
