| | Lithium sulfate monohydrate Usage And Synthesis |
| Chemical Properties | Colorless monoclinic or hexagonal crystals; transforms to cubic form at 500°C; refractive index 1.465; density 2.221 g/cm3; sublimes at 845°C; soluble in water, solubility decreases with an increase in temperature (26.1 and 23.2 g at 0 and 100°C, respectively); insoluble in absolute ethanol and acetone.
The monohydrate constitutes colorless monoclinic crystals; refractive index 1.465; density 2.06 g/cm3; loses water of crystallization at 130°C; soluble in water, (more soluble than the anhydrous salt (34.9 and 29.2 g/100g at 25 and 100°C), respectively; insoluble in acetone and pyridine.
| | Uses | Lithium sulfate monohydrate may be used in the preparation of Cu(II) doped lithium sulfate monohydrate (LSMH) crystal. | | Uses | Lithium sulfate monohydrate is used in solar panels and potential for a new class of battery. It is also used to treat bipolar disorder and in ultrasound-type non-destructive testing. It is also used as an additive for portland cement to speed up the curing. It is also involved as a catalyst in the elimination reaction for the conversion of n-butyl bromide to 1-butene. | | Uses | Lithium sulfate monohydrate is used in making a special type of high strength glass. It also is used in medicine as an antidepressant,used in preparation of lithium standard solutions.
| | Preparation | Lithium sulfate is prepared by neutralization of lithium hydroxide or lithium carbonate with sulfuric acid followed by crystallization:
2LiOH + H2SO4 → Li2SO4 + H2O
Li2CO3 + H2SO4 → Li2SO4 + CO2 + H2O
The product obtained from crystallization in a concentrated solution is the monohydrate, Li2SO4•H2O. Anhydrous salt is obtained by heating the monohydrate in a vacuum.
