Abstract: The invention relates to a process of eliminating high chloride-containing incinerator ash and incinerator ash-residue mixtures, without generating excessive heavy metal-containing effluents during the actual vitrification of the ash. The process involves first pretreating the incinerator ash or ash-residue mixture, if needed, whereby the resultant ash contains less than about 3% halogen by weight and less than about 3% C.. Following the pretreatment, the ash is dried and then mixed with any additives needed to make up a vitrifiable batch mixture which will, when subsequently vitrified, form a glass possessing an excellent acid durability. A durability whereby such that the weight loss of the glass in 5% HCI solution at 95 C is 2.0 mg/cm2 or less in 24 hours. This durability results in minimal or non-detectable leaching of hazardous heavy metal or non-metallic specie and is sufficient enough durability such that the vitrified glass will easily pass the EPA's test for leachability. A suitable glass meeting the requirements is comprised of, expressed in terms of weight percent, about 47-76% SiO2, 0.8-29% Al2O3, 3.4-33.0% CaO, and optionally 0-25% R2O, wherein R2O is selected from the group consisting of Na2O, Li2O and K2O, 0-5% Fe2O3, 0-18% B2O3, 0-7% ZrO2, 0-7% TiO2, 0-10% MO, wherein MO is selected from the group consisting of MgO, BaO, ZnO or SrO, 0-8% of at least one member selected from the group consisting of PbO, CdO, Cr2O3, CuO and NiO, 0-4% SO3 with 0-4Y% Cl+F as batched.

Abstract: This invention relates to glass frit compositions free from lead and cadmium which, when combined with an organic medium and fired to a glaze, yield a glaze exhibiting a grayish discoloration caused by the presence of a carbonaceous residue therein. The grayish discoloration can be eliminated by incorporating tin oxide in the frit composition which acts to catalyze the oxidation of and/or to directly oxidize that carbonaceous residue.

Abstract: Inorganic reinforcing fibers provided with a multilayer protective coating comprising a boron nitride sublayer and an oxide-based overcoating of alumina or synthetic mica, and fiber-reinforced ceramic matrix composite products incorporating the protectively-coated fibers, are disclosed. The fibers offer improved oxidation resistance and good compatibility with oxide-based glass and glass-ceramic composite matrix materials.

Abstract: An electrode (10) for deionization of water is made of a continuous activated carbon structure. The activated carbon is derived from a synthetic carbon precursor. The structure has openings, inlet (17) and outlet (16) ends such that water entering the inlet end passes through the openings (12) and exits through the outlet end (16), a conductive coating (17) on at least part of the outer surface of the structure, and a metal wire (19) in contact with the structure (10). A deionization system is made up of the electrodes (10) in series so that the outlet end of one electrode (10) is next to the inlet end of the nearest downstream electrode (10). The metal wire (19) of each electrode is connected to a power source. A method of removing ions from water involves removing air from the system, passing a current through the device, and passing a stream of water containing ions through it to remove the ions.

Abstract: A plasticizable raw material batch mixture for forming a silicon carbide honeycomb structure comprising the following components: (1) powdered silicon metal; (2) a carbon precursor comprising a water soluble crosslinking thermoset resin having a viscosity of less than about 1000 centipoise (cp), and preferably less than about 500 cp; (3) a powdered silicon-containing filler; and, (4) a water soluble thermoplastic binder. Optionally, the batch mixture can include either, or both, an organic fibrous filler and a pore-forming filler comprising either a graphitic or a thermoplastic pore-forming filler. In another aspect, the invention provides for a process for producing a silicon carbide honeycomb structure utilizing the inventive batch material involving mixing together selected raw materials to form the previously mentioned plasticizable raw material batch and shaping the batch mixture to form a shaped green body, preferably extruding to form a honeycomb structure and thereafter drying, curing and sintering the green body at a temperature sufficient to convert the green body to a porous silicon carbide sintered body; preferably this temperature is above about 1400 DEG C.
