PURPOSE:To improve the effective permeability and the productivity of the title molding material by a method wherein the amorphous alloy powder, on which an oxidizing treatment is conducted on its surface by rapidly heating and quenching it, and high molecular material are kneaded. CONSTITUTION:Rolls 1 and 2, which are formed by the thermal insualting material such as graphite, boron nitride and the like, are arranged with a microscopic gap, and the fused alloy 4 filled in a nozzle 3 is jetted out into the gap. The cavitation of fused alloy 4 in two rolls is generated, the amorphous alloy powder jetted out in fine powder is cooled on a cooling plate 5, and amorphous alloy powder is formed. This amorphous alloy powder is quickely inserted into the muffle furnace an shown by the arrow M1 using a jig 8, the powder is heated up quickly, it is quickly taken out as shown by the arrow M2 and quenched, and oxidation-treated. The oxidation-treated amorphous alloy powder and the high molecular material are kneaded. As a result, the molded material, having the volume ratio of 60% or higher, can be obtained. |
