Buy low price INR 285 Magnesium Carbonate MgCO₃ Block for Fireproofing, Insulation, Gymnastics, climbing, weightlifting, Ceramic and refractory manufacturing at Wedge India. Magnesium Carbonate (MgCO₃) blocks are solid, white, odorless, and non-toxic mineral products designed for use in high-temperature, chemical, and construction environments. These blocks are known for their excellent thermal decomposition, alkaline buffering, and fire-retardant properties, making them suitable for a wide range of industrial applications.

 

Key Considerations for Selection

Whiteness: For applications requiring high whiteness, such as cosmetics or pharmaceuticals, ensure the supplier provides specifications or samples confirming the whiteness level.

Thermal Stability: If your application involves high temperatures, verify the decomposition temperature and ensure the product meets your thermal stability requirements.

Purity and Grade: Depending on your application (industrial, pharmaceutical, food-grade), select the appropriate grade and purity level.

Packaging and Quantity: Consider suppliers that offer packaging sizes and quantities that suit your needs, whether in bulk or smaller quantities.
