FIELD: process engineering. ^ SUBSTANCE: invention relates to metallurgy, namely, to producing barrier metal powders. Mix containing precursor of barrier metal and nonreacting liquid diluter is fused in first reactor. Said mix is placed in at least second reactor to add reducing agent therein. Reduction of barrier metal precursor to barrier metal is conducted at temperature and in interval that allow initiating reduction reaction. Produced powder features particle shape factor f defined from REM-images in the range of 0.65ëñfëñ1.00. ^ EFFECT: powder with uniform grain size with dense size distribution containing less than 20 ppm of magnesium admixture. ^ 38 cl, 1 dwg, 2 tbl, 2 ex |
