Manganese sulfate (chemical formula MnSO4, 151.00), the first hydrate for reddish rhombic crystal, relative density 3.50, melting point is 700 ℃, soluble in water, insoluble in ethanol. It exists in the form of a variety of hydrate.
Manganese sulfate at 850 ℃ starts to break down, because of different levels, heat can be released SO3 and SO2 or oxygen, residue with manganese dioxide or four oxidation three manganese. The crystallization of manganese sulfate hydrate when heated to 280 ℃, can lose their own water of crystallization and become anhydride. [1]
Manganese sulfate is synthetic fatty acid plant need to trace elements, so the manganese sulfate as fertilizer into the soil, to increase production. Manganese sulfate added to animal feed, have the effect of fattening. Manganese sulfate is the preparation of manganese salt raw materials and other analytical reagent. In electrolytic manganese, dyestuff, papermaking and ceramics are used in industrial production of manganese sulfate.
Because of easy deliquescence, suitable scope is limited. Manganese sulfate non-combustible, stimulative. Inhalation, ingestion or percutaneous absorption of harmful, stimulative effect. Inhale dust the goods for a long time, can cause chronic manganese poisoning, the early is given priority to with neurasthenia syndrome and neural dysfunction, parkinsonism syndrome in late. Have harm to the environment, the water can cause pollution.
