Abstract
Flexible ceramic/organic webs are prepared by coating, using fixed nip techniques, a highly viscous, thixotropic material over at least two sides of an organic, thermoplastic substrate. The substrate, having fibers randomly arranged, highly dispersed and bonded at the filament junction, is the type which disintegrates at highly elevated temperatures. The resulting material is highly loaded with ceramic particles such that greater than 70 percent of the total weight of said web is ceramic material. Webs prepared in accordance with the present invention can be shaped into a variety of desired configurations and then fired at highly elevated temperatures causing the substrate to disintegrate, to thereby form ceramic articles having very high ceramic bonding properties.
