A special property of methylammonium tungstate, so-called self-reductibility is studied in the present paper. The researchshows that the tungstate has the characteristics of self-reductibility when it is heated to certain temperature at which it automati-cally decomposes and reduces itself to lower valency tungsten oxides or even metallic tungsten in N_2. The higher the temperature,the stronger the self-reductibility. A higher temperature is necessary to form metallic tungsten. New processes for the productionof pure oxides WO_(2.72) , WO_2 and metallic tungsten W are developed on the basis of the research of self- reductibility of thetungstate.
