General description

Lithium sulfate monohydrate is an inorganic lithium salt. It is relatively stable in atmospheric conditions. It is used in building blocks and chemical synthesis.

Application

Lithium sulfate monohydrate may be used in the preparation of Cu(II) doped lithium sulfate monohydrate (LSMH) crystal.
Lithium sulfate monohydrate is used to study the interference on the salicylate method, which is used for quantifying ammonia.

Features and Benefits

Lithium sulfate monohydrate has the highest pyroelectric coefficient and remarkable piezoelectric and electro-optic properties.
