마그네슘환원에 의한 지르코늄-티타늄 합금분말 합성

Abstract

Zr-Ti alloy powders were successfully synthesized by magnesium thermal reduction of metal chlorides. The evaporated and mixed gasses of ZrCl_4+TiCl_4 were injected to liquid magnesium and the chloride components were reduced by magnesium leading to the formation of MgCl_2. The released Zr and Ti atoms were then condensed to particle forms inside the mixture of liquid magnesium and magnesium chloride, which could be dissolved fully in post process by 1~5% HCl solution at room temperature. By the fraction-control of individually injected ZrCl_4 and TiCl_4gasses, the final compositions of produced alloy powders were changed in the ranges of Zr-0 wt.%~20 wt.%Ti and their purity and particle size were about 99.4% and the level of several micrometers, respectively.
