摘要

A method for producing a homogeneous more of the substance system to hydroxide - and / or the oxide with a rod-shaped morphology, wherein the multicomponent system a first refractory metal from the group consisting of mo, w, nb, re, zr, hf, v, sb, si, al and ta and a second refractory metal from the group consisting of mo, w, nb, re, zr, hf, v, sb, si, al and ta, and wherein the first refractory metal and the second refractory metal are different, wherein the first and / or the second refractory metal as a fluorine - and / or oxifluorkomplex is present as the starting material,wherein, in the first alternative, the first refractory metal in a first flow acid solution and the second refractory metal in a second flow acidic solutionand the first flow acid solution with the first refractory metal and the second flow acid solution is mixed with the second refractory metal, so that a flow acidic mixed solution with dissolved first and second refractory metal is present,orin a second alternative the first refractory metal and the second refractory metal in an alternative flow acidic mixed solution are dissolvedandfinally, the flux acidic mixed solution or the alternative flow acidic mixed solution is precipitated with a precipitating agent, so that a homogeneous mixture of solids in a suspension is present, wherein the addition of the precipitating agent in two stages, interrupted by a stirring phase, is effected.
