    摘要: A metal article containing at least 10% interconnected porosity is produced by using a preform.To make the preform, an organic binder, a wetting agent and a granular material are mixed to obtain a mouldable paste that combines 10 vol. pct. or more of the granular material, this material dissolving easily in a liquid solvent. The paste is shaped into an aerated preform, thus creating an open pore space to be infiltrated by the metal or alloy.The wetting agent is evaporated and the preform is baked to a temperature sufficient to degrade the binder and create a network of interconnected open porosity in the preform. Then, the open pore space is filled with the liquid metal or alloy.All or part of the baked preform can be easily leached by a liquid solvent through the network of fine pores.

    摘要: The present invention relates to a combustion reactor for nanopowders, a synthesis apparatus for nanopowders using the combustion reactor, and a method of controlling the synthesis apparatus. The combustion reactor for nanopowders comprises an oxidized gas supply nozzle connected to an oxidized gas tube; a gas supply unit supplying a fuel gas and a precursor gas; and a reaction nozzle forming concentricity on an inner wall of the oxidized gas supply nozzle to be connected to the gas supply unit and having an inlet opening for supplying an oxidized gas disposed at a region adjacent to a jet orifice for spraying flames. In the present invention, it is possible to precisely control the stability of flames, the uniform temperature distribution of flames and the temperature of flames that affect the properties of nanopowders, and the deposition of oxide in the combustion reactor is prevented to thus enable a continuous and uniform reaction for a long time, thereby enabling an economic and efficient synthesis of nanopowders.

    摘要: A preform intended for the manufacture of a metal foam having a porosity of between 62% and 85%, the preform including a set of precursors in the form of balls formed of a mixture of 12% to 25% of organic binder, 72% to 87% of sodium chloride and 1 to 3% of kalinite. The precursors have a diameter of around 1 mm to 10 mm, and preferably 4 mm, the precursors being obtained by granulating the mixture using a fluidized bed process.
