Stability:
1. The aqueous solution is neutral, with a pH of 6.7 to 7.3.
2. Easily soluble in water, salty in taste; low thermal conductivity; non-conductive, triboluminescence; strong hygroscopicity, easy to deliquesce. Lithium salt is one of the most widely distributed salt minerals. It is mainly produced in marine carbonate system, clastic rock system sedimentary deposits and dry salt lake sediments in inland basins with arid climate. It is combined with gypsum, anhydrite, and polyhalite. The solubility of symbiosis such as carnallite, sylvite, glauberite, etc. in 100g water is 35.7g (20℃), 39.8g (100℃). Hardly soluble in ethanol. Soluble in glycerol (glycerol)
