Description

General description

Manganese(II) acetate tetrahydrate is an ionic compound soluble in water and polar solvents. It is commonly used as a precursor in chemical vapor deposition processes to fabricate cathode materials for lithium-ion batteries. It is also used as a sol-gel precursor to synthesize manganese oxide-based catalysts and other functional materials. Additionally, manganese(II) acetate tetrahydrate serves as a mordant in dyeing, a drier for paints and varnishes, and an oxidation catalyst. It is employed in the production of high-purity manganese dioxide, manganese oxide hydrate, and other manganese-containing compounds.

Application

Manganese(ll) acetate tetrahydrate can be used as:     

• A starting material in the synthesis of manganese carboxylates, which are used to prepare manganese oxide thin films by chemical vapor deposition (CVD).     
• A precursor in the synthesis of manganese-TiO₂ composites by chemical vapor condensation (CVC).These composites are used in the oxidation of NO at low temperatures.     
• A precursor in preparation of NCM (LiNi1/3Co1/3Mn1/3O2) powder applicable as cathode material in lithium-ion batteries.     
• A starting material for the synthesis of LiMn₂O₄ (LMO) film on Au substrate by sol-gel method.
