摘要:The method is used for the synthesis of an oxygen less powder of Aluminum Nitride. As an initial material for the reaction a bulk piece of alumina is used (e.g. in the form of a rod or ball) instead of the aluminum powder most frequently used until now. The reaction proceeds in a gas atmosphere with elevated pressure from 10 to 10 000 atm of nitrogen with 5 to 95 % dopes of the nobel gases (e.g. argon, helium) in the temperature region from 200° to 2200 °C. The product of the reaction is a fine powder of Aluminum Nitride.

摘要:A process for preparing catalytically active coatings for the synthesis of hydrogen cyanide on moulded items substantially consisting of aluminum oxide. The catalytically active coatings contain, as active components, at least one platinum group metal and a nitride waich are applied to the moulded item by means of a coating dispersion which contains the active components as finely divided solids. This means that the hitherto conventional production of aluminum nitride during the forming process is not required. The coatings therefore achieve their final activity level, which is well above that of conventional coatings, very rapidly. In addition, these catalysts can be started up under high load and have a lower operating temperature.

标题 :Methods for the manufacturing of nanostructured metals, metal carbides, and metal alloys

摘要:Methods for the manufacture of nanostructured metals, metal carbides, and metal alloys are presented, such metals including nanostructured aluminum, chromium, iron, molybdenum, vanadium, and steel. Preferably, the nanostructured steel is of the M50 type, and comprises iron, molybdenum, chromium, vanadium and carbon. Synthesis of M50 steel further comprising nanostructured aluminum, aluminum oxide, or aluminum nitride is also described. In accordance with an important feature of this invention, the grain size of the metals and metal alloys is in the nanometer range. In accordance with the method of the present invention, the nanostructured metals, metal carbides, and metal alloys are prepared via chemical synthesis from aluminum, iron, molybdenum, chromium and vanadium starting materials. Decomposition of metal precursors or co-precipitation or precipitation of metal precursors is followed by consolidation of the resulting nanostructured powders. Alternatively, nanostructured M50 steel may be obtained by mixing of nanocrystalline chromium, iron, molybdenum, and vanadium powders, followed by ball-milling, and consolidation. The nanostructured metals, metal carbides, and metal alloys of this invention find particular utility in the manufacture of cutting tools and bearings, and in ferrofluids, magnetic memory systems, and catalysis.

摘要:This invention provides a method for production of AlN powder. An Al powder was poured into a refractory container having an opening end. If the packing density of the Al powder was less than 0.8 g/cm 3 , the container containing the Al powder was placed in a reaction chamber filled with nitrogen. If the packing density was larger than 0.8 g/cm 3 , porous aluminum tubes were placed vertically in Al powder or an initiator was placed on top of the Al powder or both were taken. The container was then placed in the reaction chamber filled with nitrogen. A nitrogen stream was allowed to flow through the Al powder from the bottom to the top and the combustion synthesis reaction was ignited by heating the top surface of the reactant powder.

标题:Synthesis of oxygen and boron trihalogenide functionalized two-dimensional layered materials in pressurized medium

摘要:A method that uses a pressurized reactive medium composed of inert solvents such as pressurized liquid or supercritical fluid carbon dioxide (C02), and sulfur hexafluoride (SF6) and reactive dissolved species ozone (03) and/or boron trifluoride (BF3) and general boron trihalogenides (BX3) to react with two-dimensional (2D) layered materials and thereby synthesize covalently oxygen and/or BX3 functionalized exfoliated 2D layered materials. When 2D layered materials are dispersed in these reactive liquids or fluids by ultrasound sonication or high shear mixing, a simultaneous covalent functionalization and exfoliation of the 2D layered materials happens. Following attainment of the required extent of functionalization and exfoliation, the unreacted 03, BX3, SF6 and C02 can be easily removed as gases by decompression leaving behind the solid phase, thereby leading to efficient and economical production of functionalized and exfoliated 2D layered materials.
