응용 분야
개요Lithium sulfate monohydrate is an inorganic lithium salt. It is relatively stable in atmospheric conditions. It is used in building blocks and chemical synthesis.
용도Lithium 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.
제조 방법
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.
