Calcium nitrate, also known under the traditional name "calcium nitrate", "lime or calcium nitrate" is an inorganic salt of nitric acid, is a colorless cubic crystals.The compound is highly hygroscopic.Density compound - 2.36 g / cm³, a melting point - 561 ° C, boiling point - 151 ° C.Under normal storage conditions is nonflammable flameproof agent.In the temperature range -60 ° C - +155 ° C manifested stability that distinguishes calcium nitrate.Formula chemical compound - Ca (NO3) 2.
Get calcium nitrate absorption of nitrogen oxides milk of lime or limestone in the influence of HNO3.The granulated calcium nitrate produced by the method of low-temperature neutralization of HNO3 natural limestone.
Calcium nitrate - a universal physiological alkaline fertilizer, suitable for soils with low calcium content.Calcium nitrate is suitable for all soils.Especially appropriate to its application to the acidified, sandy, alkaline soils.Calcium is needed for the proper and healthy development of the plant tissues, raising the strength of their cell walls, improving the quality of the fruit.Calcium nitrate improves the marketability of products, extends shelf life.It is also used for the prevention of diseases provoked by a lack of calcium (core or apical rot, regional burn leaves and other).The fertilizer is applied in liquid form.For hydroponic systems calcium nitrate - the only way to obtain a water-soluble calcium.
Preparation of the compound in the form of beads and crystals has significantly expanded the scope of its application.Granulated calcium nitrate is not compressed, not hygroscopic, easy to use.
crystalline calcium nitrate is widely used in construction and industry.It is a complex additive introduced into the concrete and mortars in order to improve their properties in the construction of monolithic concrete and reinforced concrete structures.These compounds are used as accelerators of hardening concrete.They increase the water resistance of the concrete class, extends its setting without changing the flow (rheology) through the use of plasticizers.Calcium nitrate is used in order to increase the frost resistance, strength of concrete fracture, reduce shrinkage deformation of concrete and cracking, corrosion processes slow rebar used in concrete caused by high chloride content.
It is also used in the preparation of cements which are intended for cementing oil wells at preparation processing solutions used in repairing gas wells, including drilling fluids.
Calcium nitrate is used in fireworks, as it is one of the constituent elements of explosives.However, the use of it because of the strong hygroscopic somewhat limited.
Calcium nitrate is also widely used in the manufacture of chemicals, dry mixes, glass and building materials.
