20080087135 - Microwave heating method and apparatus for iron oxide reduction: A method and apparatus for reducing iron oxides using microwave heating in a furnace chamber which is sealed against the entrance of air reduces the energy required and produces a low temperature reduction and allows the recovery of combustible synthetic gas as a byproduct of the process. Avoidance of the... Agent: John R. Benefiel

20080087136 - Ferrosilicate proppant and granule composition: There is provided a process for the thermal conversion of non-ferrous smelting slag to granular products having sufficient strength and other useful characteristics for use as proppant, gravel pack, roofing granules and abrasive blast materials. Non-ferrous smelting slag is treated with silica, alumina, calcia and magnesia and then heated for... Agent: Seed Intellectual Property Law Group PLLC

20080087137 - Method for manufacturing metal nanoparticles: The present invention relates to a method for manufacturing metal nanoparticles, more particularly to a method for manufacturing metal nanoparticles, which includes: preparing a mixed solution including capping molecules, a metal catalyst, a reducing agent, and an organic solvent; adding a metal precursor to the mixed solution and raising to... Agent: Staas & Halsey LLP

20080087138 - Production of valve metal powders: The invention relates to the production of valve metal powders, in particular, tantalum powders by reduction of a corresponding valve metal compound, for example, K2TaF7, with an alkali metal in the presence of a diluent salt, whereby the reduction is carried out in the presence of a particle diminution agent,...
