MnCO3 HS CODE 28369990 Cas no 598 62 9

Manganese carbonate CAS No.:598-62-9 Main properties and features

Manganese carbonate CAS No.:598-62-9 is rosy triangle crystal or amorphous brown powder. Calcined in the pyrolusite powder direct acidification method, which can shorten process, lower cost and reduce pollution to environment; widely used in ferrite, desulfurizatio, porcelain glaze, varnish, manganese salt, fertilizers, pharmacy and machine parts and agriculture.

Manganese carbonate (MnCO3) is an attractive anode material with high capacity based on conversion reaction for lithium-ion batteries (LIBs), but its application is mainly hindered by poor cycling performance. Building nanostructures/porous structures and nanocomposites has been demonstrated as an effective strategy to buffer the volume changes and maintain the electrode integrity for long-term cycling. It is widely believed that microsized MnCO3 is not suitable for use as anode material for LIBs because of its poor conductivity and the absence of nanostructure. Herein, different from previous reports, spherical MnCO3 with the mean diameters of 6.9 μm (MnCO3–B), 4.0 μm (MnCO3–M), and 2.6 μm (MnCO3–S) were prepared via controllable precipitation and utilized as anode materials for LIBs. It is interesting that the as-prepared MnCO3microspheres demonstrate both high capacity and excellent cycling performance comparable to their reported nanosized counterparts. MnCO3–B, MnCO3–M, and MnCO3–S deliver reversible specific capacities of 487.3, 573.9, and 656.8 mA h g–1 after 100 cycles, respectively. All the MnCO3 microspheres show capacity retention more than 90% after the initial stage. The advantages of MnCO3 microspheres were investigated via constant-current charge/discharge, cyclic voltammetry and electrochemical impedance spectroscopy. The results indicate that there should be substantial structure transformation from microsized particle to self-stabilized nanostructured matrix for MnCO3 at the initial charge/discharge stage. The evolution of EIS during charge/discharge clearly indicates the formation and stabilization of the nanostructured matrix. The self-stabilized porous matrix maintains the electrode structure to deliver excellent cycling

Chemical Properties of Manganese

Manganese, with the chemical symbol Mn and atomic number of 25, is a hard and brittle metal belonging to group 7 and d-block in the periodic table (Atkins et al., 2014; Barceloux, 1999). Manganese compounds have both oxidizing and antioxidizing properties with the following oxidation states and chemical characteristics:

1.

Manganese exhibits oxidation states from −3 to +7, the most common being +2, +3, +4, +6, and +7.

2.

The manganese compounds with the +2 oxidation state (Mn (II)) are manganese chloride (MnCl₂), manganese carbonate (MnCO₃), and manganese sulfate (MnSO₄).

3.

The manganese compounds with an oxidation state of +3 are manganese acetate (Mn(OAc)₃) and manganese (III) oxide (Mn₂O₃).

4.

Manganese dioxide (MnO₂), which catalyzes H₂O₂ into H₂O + O_2, is a well-known manganese compound with a +4 oxidation state.

5.

Permanganate, with an oxidative state of +7 (Mn (VII) compounds), is purple in color and used to make glasses violet (Patrick, 1998). The commonly known permanganate compounds are potassium permanganate (KMnO₄), sodium permanganate (NaMnO₄), and barium permanganate (BaMn₂O₈). Another manganese compound with the +7 oxidation state is manganese oxide (Mn₂O₇).

The oxidation state of manganese contributes to manganese toxicity. For example, manganese (II) compounds can be both nontoxic and toxic, whereas manganese (VII) compounds are highly oxidizing and poisonous
