Application of Lithium nitrate

Submitted by admin on Tue, 10/30/2018 - 09:31

Lithium nitrate has a molecular formula of LiNO3 and a molecular weight of 68.95.

Lithium nitrate is colorless crystal and is hygroscopic. Heat to 600 ' C decomposition. Dissolved in about 2 parts of water, soluble in ethanol. The aqueous solution is neutral. The relative density is 2.38. The melting point is about 255 ' C. Strong oxidizing, rubbing or impacting with organic matter can cause burning or explosion. Irritating.
