Calcium Nitrate Tetrahydrate 98 +% Pure

What is Calcium Nitrate?

Calcium nitrate is the calcium salt of nitric acid and has the empirical formula Ca (NO3) 2. "Lime or normal nitrate" is used as a fertilizer. The name "Norgesalpeter" comes from the Norwegians Kristian Birkeland and Sam Eyde, who developed a process to produce saltpeter.

Calcium nitrate is formed when ammonium nitrate from animal manure or urine penetrates walls with the help of moisture transported by capillary action and reacts with the lime from the cement mortar or the previously used lime mortar. This creates the so-called wall salt or wall nitrate, which slowly destroys the walls (for example of cattle sheds, cellars and toilets). Throughout history there have been saltpeters who went around scraping, cleaning and selling this blooming salt from the walls. Due to its high water attraction, it cannot be used directly, but must be converted into potassium nitrate using potash.

Due to its fluorescent properties, it was also known as Balduin's phosphor in the 17th century, after its discoverer Christian Adolf Balduin.

The tetrahydrate of calcium nitrate occurs naturally in the form of the mineral nitrocalcite.

Wall salts of a different composition are also formed when free sulfuric acid from the condensate of heating gases acts on the cement and carbonate-containing aggregates in mortar, chimney bricks and plaster. The lime in the cement is converted into gypsum and ettringite, among other things. The reaction products "float", that is, they swell and shatter the building material. Wall constructions soaked in this way can also be affected by frostbites in winter.

Calcium nitrate is a white, hygroscopic, oxidizing solid that is very easily soluble in water. It forms a number of hydrates, including a di-, tri- and tetrahydrate. The compound decomposes when heated, producing oxygen and nitrogen oxides. The tetrahydrate begins to split off water of crystallization at temperatures above 100 ° C, above 130 ° C, oxygen splits off, and from 225 ° C it begins to decompose into calcium oxide. As a tetrahydrate, it forms colorless, deliquescent, monoclinic prisms.

The tetrahydrate has a monoclinic crystal structure with the space group P21/n (space group no. 14, position 2) and is dimer. The anhydrate has a cubic crystal structure with the space group Pa3 (space group No. 205).

What is calcium nitrate used for?

In addition to its use as a fertilizer, calcium nitrate is also recommended as a component of cooling brine and latex coagulation baths. It is also used as a starting material for the production of other calcium compounds or calcium-containing materials, e.g. B. calcium phosphate, calcium silicate nanocrystals, hydroxyapatite fibers and electrically conductive ceramic materials. It is also used in the manufacture of pyrotechnic articles (blasting sludge), bone implants and in the electronics industry for radio tubes. Another application is the addition in sewers to prevent the formation of H2S. In the construction industry, calcium nitrate is used as a main ingredient in concrete hardening accelerators.
