â… . Technical properties: Molecular formular: Ca(NO2)2; Molecular weight: **2.1; Specification: industrial grade; Appearance: white or straw yellow powder; Characteristics: easily deliquesce; Relative density: 2.*3; Standard: PRC Chemical Standard HG/T********9 CAS :*********8 Calcium nitrite(based on dried basis), ≥*4% Calcium nitrate(based on dried basis), ≤4.5% Water content(based on dried basis) ≤1.0% Water insoluble content(based on dried basis), ≤0.6% 1. Use 1)Produce concrete antifreezer: calcium nitrite has high solubility, so can be made into solution or powder as demands. Using this antifreezer at negative temperature can promote the hydration of minerals in cement, and the freezing point of operative temperature can be reduced to **0οC. 2)Produce steel rust inhibitor: calcium nitrite can purify steel and protect it from rust, and can protect steel material in concrete buildings and structures from rust, to extend the useful life of concrete buildings.
