| 204 | Fabrication of reliable ceramic preforms for metal matrix composite production | US850474 | 1992-03-12 | US5360662A | 1994-11-01 | Boon Wong |
| Sintered ceramic preforms for metal matrix composites fabricated by a method comprising: (a) preparing a homogeneous mixture containing appropriate amounts of silicon-containing fibers/particulates, such as silicon carbide, at least one solvent, at least one polymer, and an oxide-containing material, such as boric acid or phosphoric acid, capable of forming a low melting silicate with a silicon oxide, such as a borosilicate; (b) shaping a green ceramic preform from the mixture, such as by injection molding; (c) removing the solvent(s) and the polymer(s); (d) oxidizing the surfaces of the silicon-containing fibers to form a layer of the silicon oxide thereon; (e) heating the preform to a temperature sufficient to react the oxide-containing material with the silicon oxide to form the low melting silicate material; (f) liquid phase sintering the fibers in the presence of liquid silicate material to strengthen the preform; and (g) cooling the sintered preform to ambient. The sintered ceramic preform prepared by this method is sufficiently strong to withstand pre-infiltration handling and squeeze casting to inject molten metal under pressure into the pores of the preform. | ||||||
| 205 | Plasma torch furnace processing of spent potliner from aluminum smelters | US868024 | 1992-04-13 | US5222448A | 1993-06-29 | George W. Morgenthaler; Jeffrey L. Struthers; George W. Carter |
| Spent potliner from aluminum reduction cells includes carbon, inorganic brick and refractory material, and fluoride, sulfur, and cyanide compounds, and is considered hazardous. It is treated by introducing it into a vessel, and exposing it to the heat of a plasma torch at a temperature of at least 1000.degree. C. As a result, carbon is gasified and converted to combustible carbon monoxide or hydrocarbons, or to carbon dioxide; inorganic material is melted form slag; fluoride compounds are melted, vaporized, or reduced to gaseous HF; cyanide compounds are destroyed; and all other materials, including sulfur compounds, are either melted or gasified. As a result, the spent potliner is rendered non-hazardous, and the quantity of remaining slag has both its solid volume and mass substantially reduced by a factor of at least 1.5:1 in mass and at least 3:1 in volume relative to the input spent potliner. The process allows gaseous fluoride compounds to be captured and thermal energy produced in the process to be extracted. The molten slag material produced within the vessel is removed from the vessel, and cooled to form a solid slag which is substantially free of cyanide compounds, resistive to leaching, and safe for disposal. The slag has commercial utility. Combustible carbon compounds can be captured and used. When carried out at an aluminum smelting site, adequate electrical power is readily available, and there is an in situ demand for recovered fluoride compounds, combustible gases, and extracted heat. | ||||||
| 206 | Method of processing contaminated mineral substances | US196995 | 1988-05-20 | US4846083A | 1989-07-11 | Harry Serbent, deceased |
| For the production of a product which can be dumped or utilized, the mineral substances are subjected in a rotary kiln to a thermal treatment at a temperature at which the charge of the rotary kiln is transformed to a pasty to liquid slag phase. The composition of the charge is so selected that a slag phase is produced in which the main components, which constitute a matrix, are in the range from 60 to 72% SiO.sub.2, 10 to 30% Al.sub.2 O.sub.3 and 5 to 25% CaO+MgO, of said matrix, wherein the total percentage of SiO.sub.2 +Al.sub.2 O.sub.3 +CaO+MgO equals 100, the total of the main components SiO.sub.2, Al.sub.2 O.sub.3, CaO and MgO amounts to more than 60% on a dry and ignition loss-free basis, of the mineral matter which is charged to the rotary kiln. The slag phase discharged from the rotary kiln is cooled and the exhaust gas from the rotary kiln is purified. | ||||||

| Solid coal combustion products, fly ash, mine tailings or the like coal byproducts are melted after their composition is adjusted to contain 40-60% SiO2; 15-40% trivalent oxides, mainly those of iron and aluminum; and 11-35% mono- and divalent oxides. After melting at 1,350*-1,500*C until the melt is substantially fined, the material is molded at 1,200*-1,400*C, then is crystallized between 900* and 1,300*C and then the crystallized object is cooled. The product contains a feldspar which is either 55-75% labradorite or 50-70% plagioclase, also 4-20% monoclinic and rhombic pyroxenes, and 2-25% oxides mainly having a spinel structure and ferric oxide modifications. Depending on the starting composition and the heat treatment that is employed, different crystal associations are obtained some of which are more useful as architectural paneling and the like, while others are more useful as items with good chemical durability.
