PREPARATION OF M003 FROM AMMONIUM TETRAMOLYBDATE IN MICROWAVE FIELDS

摘要

Decomposition of ammonium tetramolybdate to prepare M0O3 using silicon carbide crucible in microwave fields was investigated. The results were analyzed Using TG-DTG and X-ray diffraction. Meanwhile, the effects of heating rat, material thickness, socking time, socking temperature on the structure of preparing M0O3 were studied. TG-DTG curves show that the decomposition process of ammonium tetramolybdate is only one stage, in the temperature range 300-350°C, whose begin to decompose when temperature increases beyond 300°C.
