What is Manganese Carbonate CAS 598-62-9?

Manganese Carbonate, also called manganese(II) carbonate or manganous carbonate, is an inorganic manganese salt with molecular formula MnCO3 and molecular weight 114.95 g/mol. It appears as a rose-colored to light brown powder and has EINECS 209-942-9.

What manganese content should industrial Manganese Carbonate have?

Industrial grades commonly contain about 43-46% manganese, with higher-purity grades often specified around 44-48% or more. Exact content and impurity limits should be matched to the intended ferrite, feed, or fertilizer application.

Why is Manganese Carbonate used in soft magnetic ferrites?

It is a key manganese source for Mn-Zn soft ferrites used in transformers, inductors, and power electronics. When calcined, manganese carbonate decomposes into reactive manganese oxide that can combine with zinc and iron oxides to form the ferrite phase.

How is Manganese Carbonate used in fertilizer and animal feed?

In agriculture, it supplies manganese to correct deficiency symptoms such as yellowing leaves. In animal feed, it serves as a trace mineral source to support normal growth and metabolic function, with dosage based on species and formulation requirements.

What solubility and thermal properties are important for processing?

Manganese carbonate is essentially insoluble in water but soluble in dilute acids, which makes it useful for clean conversion into manganese salts. It decomposes on heating, typically above about 200 C, releasing carbon dioxide and forming manganese oxide.

Manganese Carbonate CAS 598-62-9

Manganese Carbonate CAS 598-62-9 is an inorganic manganese salt chemically defined as Manganese(II) carbonate , functioning primarily as a precursor for the synthesis of manganese oxides in soft magnetic ferrites and as a nutritional trace element in animal feed. Also known as Manganous carbonate or Carbonic acid manganese salt, this rose-pink crystalline powder is utilized to manufacture high-performance magnetic cores for electronics and serves as a pigmenting agent in ceramic glazes and concrete staining. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

Key Application Fields

Manganese Carbonate is valued because it is a stable, non-hygroscopic source of manganese that reacts cleanly in acidic environments.

1. Magnetic Materials (Ferrites) This is one of the most critical applications. High-purity Manganese Carbonate is a key ingredient in the production of Soft Magnetic Ferrites (Mn-Zn ferrites). These components are essential for transformers, inductors, and power supply units in the electronics industry. Our product’s low impurity profile ensures optimal magnetic permeability.

2. Agriculture and Animal Feed Manganese is a vital micronutrient.

Fertilizers: It is used to cure manganese deficiency in crops (often seen as yellowing leaves), particularly in soil with high pH.
Feed Additive: It serves as a nutritional supplement for livestock to support bone development and enzyme function.

3. Ceramics and Glass

Glazes: In pottery and tile manufacturing, it acts as a colorant. Depending on the firing atmosphere and other ingredients, it can produce reddish-browns, blacks, or purples.
Porcelain: It is used to minimize the “iron spotting” effect, ensuring a cleaner finish.

4. Chemical Intermediate It is the preferred starting material for manufacturing other manganese salts (like Manganese Nitrate or Manganese Gluconate) because it dissolves in acid without introducing sulfate or chloride ions, releasing only carbon dioxide.

Why Sourcing the Right Grade Matters

Not all Manganese Carbonate is suitable for all applications.

For Electronics: You need low silica and low sodium levels.
For Agriculture: You need strict control over heavy metals like Lead (Pb) and Arsenic (As).

We supply grades that are tailored to these specific needs, ensuring you don’t pay for purity you don’t need, or risk using a low-grade product in a sensitive application.

Safety and Precautionary Measures

While Manganese Carbonate is stable, it should be handled with standard industrial hygiene practices.

Dust Control: Long-term inhalation of high concentrations of manganese dust can be harmful to the nervous system. Local exhaust ventilation is highly recommended in mixing areas.
PPE: Operators should wear dust masks (N95), safety goggles, and gloves to prevent irritation.
Incompatibility: Avoid contact with strong acids unless part of the controlled reaction process, as this will generate carbon dioxide gas rapidly.

Storage and Stability

One of the benefits of Manganese Carbonate over other manganese salts (like the sulfate form) is that it is not highly hygroscopic (it doesn’t absorb water easily).

Environment: Store in a cool, ventilated, and dry warehouse.
Separation: Keep away from acids to prevent accidental reaction.
Packaging: Keep containers (bags or drums) tightly closed to prevent dust contamination.
Shelf Life: It is chemically stable and has a long shelf life (2+ years) if stored correctly.
