Abstract: A method for making high temperature filter media includes the steps of melt-spinning a plurality of fibers of pre-ceramic thermoplastic polymer to form a non-woven textile web of the fibers, curing and cross-linking the thermoplastic polymer to a thermo-set polymer and thermally decomposing the thermo-set polymer to ceramic.

Abstract: Hafnium containing preceramic polymer is made through the reaction of hafnium halide compound with any of the following compounds: ethylene diamine, dimethyl ethylene diamine, piperazine, allylamine and or polyethylene-imine.

Abstract: A process for fabricating ceramic composites employs a thermoplastic photo-curable pre-ceramic polymer in which the component is shape by a variety of standard composite fabrication techniques, such as filament winding, tape winding, and woven cloth winding. The process includes steps of passing ceramic fiber monofilament, tow, mat, or woven cloth through a solution of said thermoplastic photo-curable pre-ceramic polymer, applying ceramic fiber monofilament, tow, mat, or woven cloth to a moving flat substrate, using a compaction roller to press the thermoplastic pre-ceramic polymer coated ceramic fiber onto flat substrate using photo-light of the ultraviolet, visible, or infrared light spectrum to induce cross-linking (curing) of the photo-curable pre-ceramic polymer thereby rendering a thermoset polymer and either partially or completely pyrolyzing the now cured pre-ceramic polymer matrix coated ceramic fiber material.

Abstract: A process for synthesizing photocurable poly(ethynyl) carbosilane includes the steps of mixing dichlorosilane and trichlorosilane reagents, adding sub-stoichiometric amounts of alkali metal and adding excess sodium acetylide.

Abstract: Disclosed is a radiant burner with a burner chamber and a gas-permeable burner plate made of ceramic or metal, especially for cooking areas or individual cooking locations, the heating surface of which is composed of glass ceramic, the gas-permeable burner plate having regions of different gas permeability.

Abstract: An improved method for the fabrication of a reinforced composite. The method includes assembling rigid rods into a geometric structure such that all interstitial voids are interconnected, infiltrating the geometric structure with particles, impregnating the infiltrated geometric structure with an appropriate liquid matrix binder or precursor, and treating the impregnated geometric structure such that the binder solidifies to form the reinforced composite.
