light pink monoclinic fine crystals. The relative density was 2. 95. Soluble in water, insoluble in ethanol. When heated above 200 ° C., the crystal water begins to be lost, and most of the crystal water is lost at about 280 ° C. At 700 ° C, an anhydrous salt melt is formed. 850 degrees began to decompose, due to different conditions and the release of sulfur trioxide, sulfur dioxide or oxygen, the residual black insoluble manganese tetroxide is completely decomposed at about 1150.

is one of the important trace element fertilizer, which can be used as base fertilizer, seed soaking, seed dressing, topdressing and foliar spraying, which can promote crop growth and increase yield. In animal husbandry and feed industry, used as feed additives, can make livestock and poultry develop well, and has the effect of fattening. It is also a raw material for processing paint and ink drying agent manganese naphthalate solution. It is used as a catalyst in the synthesis of fatty acids. In addition, it can also be used as raw materials for paper making, ceramics, printing and dyeing, ore flotation, electrolytic manganese production and other manganese salt production.
packed in woven bags lined with polyethylene plastic bags, each with a net weight of 50kg. Store in a ventilated, dry warehouse. Prevent weathering and moisture. Protection against rain and sun exposure during transport. When loading and unloading should be light to prevent packaging damage. The stacking height should be 5 packs. In case of fire, it can be suppressed by water, sand and all kinds of fire extinguishing. Toxicity and protection: see manganese metal.
