Colorless crystals;.
There are three crystal forms, α, β and γ. The α type is a white monoclinic crystal, the β type is a hexagonal crystal, and the γ type is a cubic crystal. It is hygroscopic and the monohydrate crystallized from the concentrated aqueous solution is very stable.

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.
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.
