20090295045 | PROCESS FOR MAKING CERAMIC INSULATION - A method is provided for producing insulation materials and insulation for high temperature applications using novel castable and powder-based ceramics. The ceramic components produced using the proposed process offers (i) a fine porosity (from nano-to micro scale); (ii) a superior strength-to-weight ratio; and (iii) flexibility in designing multilayered features offering multifunctionality which will increase the service lifetime of insulation and refractory components used in the solid oxide fuel cell, direct carbon fuel cell, furnace, metal melting, glass, chemical, paper/pulp, automobile, industrial heating, coal, and power generation industries. Further, the ceramic components made using this method may have net-shape and/or net-size advantages with minimum post machining requirements. | 12-03-2009 |
20100109209 | METHOD FOR THE PRODUCTION OF COMPONENTS MADE OF CERAMIC-MATRIX COMPOSITE MATERIAL - A method for the production of components made of ceramic-matrix composite material, in the fields of aerospace engines and turbines and turbine systems and plants; according to the method, a preform of ceramic fibres is shaped and set in a draining mould, for example made of plaster; the fibres of the preform are impregnated with a suspension of ceramic powders, the liquid of which is drained by capillarity from the draining mould; simultaneously to draining, a suspension of ceramic powders is infiltrated between the fibres of the preform so as to fill the empty space left by the drained liquid; at the end of the steps of draining/infiltration a body is obtained with a solidified or compacted porous matrix, which is removed from the draining mould and is sintered. | 05-06-2010 |
20110101575 | PREFORM FOR COMPOSITE MATERIAL AND PROCESS FOR PRODUCING THE SAME - A preform for a composite material which has high strength and excellent air permeability and hence is applicable to a high-speed die casting method and which is capable of forming a metal composite material having excellent mechanical properties by a high-speed die casting method. Also provided is a process for producing such a preform. Ceramic fibers or/and ceramic particles are mixed with a silica sol and calcium carbonate and sintered at a predetermined temperature to form a calcium/silicon sinter obtained from the silica sol and calcium carbonate. The calcium/silicon sinter coats the ceramic fibers or/and ceramic particles so that a preform having the fibers or/and the particles bound to each other by the calcium/silicon sinter is obtained. The preform for a composite material has high strength and excellent air permeability and is applicable to the high-speed die casting method capable of attaining high productivity. | 05-05-2011 |
20120267833 | METHOD OF FORMING A WOVEN FIBER STRUCTURE USING A TACKIFIER COMPOSITION - A method of forming a woven fiber structure for a molding process to produce a ceramic matrix composite, includes depositing a tackifier composition having a carrier solvent, a resin material, and an inorganic filler onto at least a portion of a woven fiber structure; drying the tackifier composition on woven fiber structure to remove at least a portion of the carrier solvent from the tackifier composition; and forming the dried woven fiber structure into a preform. | 10-25-2012 |
20140084521 | Method For Producing A Composite Including A Ceramic Matrix - A method for producing a part made of ceramic matrix and ceramic fibres composite material. It comprises: the formation of a fibrous preform by intertwining threads constituted of ceramic material fibres on a contact surface of a support element reproducing the internal and/or external shape of the part to be produced; the partial densification of the fibrous preform at a temperature below the melting temperature of the material of the support element and below the melting temperature of the material of the fibres of the preform, said partial densification resulting in a consolidated fibrous preform comprising a matrix volume fraction above 5% and at the most equal to 40% of the matrix volume of the part to be produced; the removal of the support element from the consolidated fibrous preform by chemical attack of the contact surface of the material of the support element; the densification of the consolidated preform, carried out at a temperature below the melting temperature of the fibres of said preform. | 03-27-2014 |
20160145157 | Method of Making Controlled Morphology Metal-Oxides - A method of making metal oxides having a preselected morphology includes preparing a suspension that includes a solvent, polymeric nanostructures having multiplicities of hydroxyl surface groups and/or carboxyl surface groups, and a metal oxide precursor. The suspension has a preselected ratio of the polymeric nanostructures to the metal oxide precursor of at least 1:3, the preselected ratio corresponding to a preselected morphology. Subsequent steps include depositing the suspension onto a substrate, removing the solvent to form a film, removing the film from the substrate, and annealing the film to volatilize the polymeric nanostructures and convert the metal oxide precursor to metal oxide nanoparticles having the preselected morphology or to a metal oxide nanosheet including conjoined nanoparticles having the preselected morphology. | 05-26-2016 |

20100001441 | Brick Manufacturing Process Employing Cuttings of Geological Silts and Drillings Obtained From Drilling Operations - A procedure for manufacturing bricks from geological silts and drillings obtained from drilling operations is described, which comprises the step of mixing a volume of geological cuttings obtaining through the discarded material from the drilling of a well, such a as a water well, hydrocarbon prospecting, or any other fluid prospecting well. The geological cuttings are made of sands and geological clays, and they are then mixed in adequate proportions with commercial clays, fibrous organic material and water, until reaching the necessary plasticity allowing performing the subsequent molding operation with said mixture. The molded blocks and bricks thus obtained are then subjected to a baking thermal operation, obtaining desiccated bricks and blocks with the necessary mechanical resistance properties and hardness as required by a building material. | 01-07-2010 |
