5401696 CERAMIC COMPOSITE Montgomery Lionel Bay Village, OH, UNITED STATES Assigned to Advanced Ceramics Corporation A ceramic composition and method for making ceramic composites having superior erosion and corrosion resistance to molten metal. The composite includes mullite, aluminum nitride and boron nitride in combination. The composite may be hot pressed or cold formed and pressureless sintered into a desired shape.
Method of preparing a composite material comprising a silica network and chains of a polyhydroxy compound which are interwoven therewith and a liquid crystal display device having a top coat of such a composite material. A description is given of a method of preparing a composite material comprising a silica network and, interwoven therewith, chains of, for example, polyhydroxyalkyl acrylate, by first photopolymerizing a tetraalkenyl orthosilicate with UV-light and subsequently converting it into the composite material by subjecting it to a sol-gel treatment. The material obtained is optically transparent. In addition, the material exhibits very little shrinkage so that it can be deposited on a substrate in relatively thick layers. The composite material is very suitable for a top coat 5 on a color-filter layer 3 in a liquid crystal display device because, inter alia, it adheres well to the IT0 layer 7.
5437898 5437852 WATER-SOLUBLE PRE-CERAMIC POLYMERS AND METHODS OF THEIR PRODUCTION Pak Sung S; Tolley Archie N Evington, VA, UNITED STATES Assigned to The Babcock & Wilcox Company A method of making water soluble pre-ceramic polymers includes heating hydrated metal salts above their melting points. A flow of air drives off water and most of the ligands. Polymerization occurs in the melt and the remaining side groups make the polymer soluble in water. Solubilization in water is accomplished by mixing the polymer with distilled water and heating the mixture at a temperature higher than about 60 degrees C. Thus prepared polymer solutions may be used to form fibers, films, and composite matrices.
CERAMIC VENEER COMPOSITE STRUCTURE Forry John S; Simonton Thomas C; Welch William; Wisnosky Jerome D Lancaster, PA, UNITED STATES Assigned to Armstrong World Industries Inc A print and fusion process is used to fabricate ceramic elements that are subsequently utilized to generate a composite including a fibrous mat and discrete ceramic elements. The composite may include a substrate and a flexible or rigid non-ceramic composition between the discrete ceramic elements and/or the substrate. A ceramic ink preferably partially penetrates the fibrous mat to form the discrete elements or a continuous layer.
