摘要： Disclosed is a method for manufacturing a billet using aqueous salt solutions. The method for manufacturing a billet using aqueous salt solutions, comprising the following steps of: infiltrating aqueous salt solutions into metal powders or cut metal wires by adding the solutions to metal powders or cut metal wires filled in a cylindrical container, to obtain a mixture of aqueous salt solutions infiltrated into the metal powders or metal wires; evaporating water in aqueous salt solutions by heating said container containing the mixture, to obtain a dried mixture; and separating said dried mixture of metal powders or metal wires and salts from the container, to obtain a billet.

摘要： A method for making porous metals that can be used as a filter, a sound-absorbing plate and a line material for a heat exchanger, is manufactured in a simple process using metal powder. The method includes the steps of heating a mixture of a powder-shaped salt and metal powder at a temperature lower than a melting temperature of the salt and higher than a melting temperature of metal powder, to thereby melt the metal powder, pressing and molding the mixture so that the fusion metal is filled into the powder-shaped salt, and erupting the salt from, the plastic body to thereby obtain porous metal. The porous metal having a simple process and a reduced production cost, has an advantageous competitiveness over any or methods for use in a sound-absorbing material or a line material of a neat exchanger, in view of a high pore ratio and a specific surface area.
