PHASE TRANSFORMATION OF THE MICRO-POWDER AMMONIUM TETRAMOLYBDATE IN AQUEOUS SOLUTION

摘要

The phase transformation of the micro-powder ammonium tetramolybdate in acidic solution was studied and one phase of ammonium tetramolybdate, which has not been reported before, was crystallized. The possible reason why the phases of ammonium tetramolybdate crystallized from aqueous solution changed with the crystallization conditions was proposed based on the structure characteristics of the Mo(VI) isopolyacidic anions.
