Trace Elements
Manganese chloride tetrahydrate
Manganese chloride tetrahydrate is soluble in water and alcohol, but insoluble in ether. It has hygroscopicity and is prone to deliquescence. At 106℃, it loses one molecule of crystalline water, and at 198℃, it loses all the crystalline water to form an anhydrous form.
Manganese sulfate monohydrate is light pink powder with pungent odor. It is a kind of important trace element in agriculture. Its melting point is around 700℃, and solute in water easily, as well as methanol, but hard to solute in diethyl ether. The density is 2.95g/cm3. Its melting point is 700℃. It is soluble in water, insoluble in alcohol.
Manganese chloride is pink powder with high hygroscopic; melt at 650℃ and sublimed at above 650℃; will release chlorine hydride gas and generate trimanganese tetroxide when heated in the air.
Manganese chloride monohydrate
Manganese chloride monohydrate has good stability at room temperature. It remains stable in the air, but decomposes and releases chlorine gas when heated. Manganese chloride monohydrate is soluble in water and the solution appears pale pink.
Colorless, or slightly colored transparent or translucent syrupy solution. The main source of potassium silicate products is silicon and highly soluble potassium, which can be assimilated by plants, it mainly stays in roots, leaves and bracts (inflorescence). It depositions in the plant’s bureaucratic, cell wall, cell gap and outer layer in the form of amorphous, and no longer move after deposition, no longer re-allocation.
It is white crystalline powder. Its density is 2.37 g/mL at 25 °C, pH is 9.0 to 10.0. The melting point is 687℃.
Zinc sulphate has good water solubility, and can be absorbed by the crop easily. It can cure the disease such as little-leave disease, clustering-leave disease, little shape disease, ununiform shape disease, grain scattered disease cause by the deficiency of the Zinc. The density is 1.966g/cm3. Its melting point is 100℃, boiling point is 500℃.
