Manganese Tungstate

Besides, at low temperature manganese tungstate is the anti-ferromagnetic materials and English alias is manganese (II). Its physical properties are as follows: chemical formula: MnO4W, molecular weight: 302.78, density: 7.324g/ml, Solubility: insoluble, CAS registry number: 14177-46-9, MDL number: MFCD00014212. MnO4W is stable at room temperature and atmospheric pressure, but to avoid contact with the light, open flame and high temperature, so it should be sealed and stored in some place where is cool and dry. In addition, MnO4W have some irritation, a person's skin and eye contact product will cause inflammation and other symptoms, so during the operation should to wear some protective gear. And it has a certain degree pollution of water, we can not let undiluted or large number products to reach ground water, water course or sewage system. What’s more without government permission do not allow this material release into the surrounding environment.
Manganese tungstate synthesis method:
1. Dichloride manganese and sodium tungstate cause metathesis reaction to obtain manganese tungstate precipitate and then after washing to dried at 1000 ℃.
2. Heat the calculated amount of MnCO3 and WO3 to produce yellow-brown manganese tungstate.
