UREA

Urea is a kind of high concentration nitrogen fertilizer, which is a kind of neutral quick effect fertilizer and can also be used to produce many kinds of compound fertilizer.Urea is applicable to all crops and all soils, can be used as base fertilizer and fertilizer, dry paddy fields can be applied.No harmful substances remain in the soil and there is no adverse effect on long-term application.Animal husbandry can be used as feed for ruminants.


Chemical Formula:Co (Nh2)2
Molecular Weight:60.055
CAS NO.:57-13-6
Appearance:White prilled crystal
Density:1.32 g/m3

Property:It is soluble in water and alcohol. Its water solubility is faintly alkaline. It decomposes when heated over fusing point. Under high temperature, it can undergo a condensation reaction and form biuret, triuret and polyhydrocyanic acid.

Uses
Urea is a high concentration of nitrogen fertilizer, is a neutral organic fertilizer, also can be used in the production of a variety of compound fertilizer. In industry, for steel, stainless steel chemical polishing has whitening effect, used as a corrosion inhibitor in the metal pickling, also used in the preparation of the palladium activation fluid.
