Beschreibung

Anwendung

Lithium carbonate is an inorganic compound and serves as the precursor for the synthesis of several lithium compounds including Li-ion battery materials. It is also used in the glass and ceramic industry.

Lithium carbonate is used

• In the synthesis of monoclinic phase lithium zirconate by heating with a mixture of zirconia and potassium carbonate at high temperature.
• As a lithium precursor to synthesize solid-base catalyst [Li₄SiO₄] by simple solid-state reaction with rice husks. Li₄SiO₄ is used for biodiesel production.
• In the synthesis of high-purity lithium hydroxide monohydrate by membrane electrolysis process using lithium sulfate as electrolyte.
