Calcium Nitrite
CAS No.: 13780-06-8
Molecular formula: Ca(NO2)2
Molecular weight: 132.09
Properties: colorless or slightly yellow crystal, deliquescent.
Application: Calcium nitrite is widely used in reinforced concrete engineering. It is used as cement hardening accelerator and anti-freeze rust inhibitor. For every 2% calcium nitrite added to concrete, the life of the constructed reinforced concrete building structure can be increased by 15 to 20 years. It can also be used as a corrosion inhibitor for the pharmaceutical industry, organic synthesis and lubricating oils.
