Nitrite's success as a corrosion inhibitor for the protection of embedded steel in reinforced concrete comes from the "smart" behavior of the AFm phase (AFm is shorthand for a family of hydrated calcium aluminate hydrate phases: aluminate-ferrite-monosubstituent phases) normally it stores nitrite in preference to sulfate, carbonate, and hydroxyl ions so that the nitrite concentrations of pore fluid are low. It also work as metal corrosion inhibitor, so it can protect steel in concrete buildings and structures from rust, to extend life of specific buildings. It can promote the hydration of minerals in cement using this antifreeze at sub freezing temperature, the operative temperature can be reduced to −20 ☌. It can be use as antifreeze due to its high solubility, either in solution or powder. Ĭalcium nitrite has a great variety of uses. After, the double salt is dissolved liberating calcium nitrite and regenerating the calcium hydroxide. Essentially the function of calcium hydroxide is to carry calcium nitrite calcium hydroxide forms the insolubilized double salt which can be used to separate from calcium nitrite portions from the solution. Īlso, it can be prepared as detailed below, forming a solution of sodium nitrite and calcium nitrate cooling the solution to precipitate sodium nitrate forming a double salt of calcium nitrite/calcium hydroxide and in the presence of water, decomposing double salt to form a solution of calcium nitrite and insolubilize calcium hydroxide. At the acid plant, ammonia is burned to produce the NO X gas for acid as well as calcium nitrite. One is by reacting hydrated lime with NOX gas, which typically comes from a nitric acid plant. This facilitates the electronic transfer and increases the kinetic of the oxidation reaction.Ĭalcium nitrite can be produced by different synthesis processes. Nitrite (III) is a stronger oxidizer than nitrate (V) because at valence III it has less electrons to recover than nitrate at valence V and so the number of electrons to capture is lower. It is also characterized for its strong oxidizing character. Its melting point is of 390 ☌ and it is stable under ordinary conditions of use and storage. It is freely soluble in water with a density of 2.26 g/cm 3. Properties Īt room temperature and pressure, the compound is an odorless white or light yellowish powder. It has many applications such as antifreeze, rust inhibitor of steel and wash heavy oil. In this compound, as in all nitrites, nitrogen is in a +3 oxidation state. Cesium Nitrate Powder SpecificationĬesium Nitrate is used in pyrotechnic ingredients as colorants and oxidants, such as in bait bombs and flares.Calcium nitrite is an inorganic compound with the chemical formula Ca(NOĢ. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. Ultra-high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Cesium Nitrate is widely applied in glass, electronic and chemical industries.Ĭesium Nitrate is generally immediately available in most volumes. It’s the raw material of various flameproof glass and catalysts. Cesium Nitrate, or Caesium Nitrate, is a compound that is highly soluble in water.
