"Caustic calcined magnesia segment is projected to exhibit a significant CAGR between 2025 and 2030"
In the global magnesium oxide (MgO) market, the caustic calcined magnesia segment is estimated to record a significant CAGR during the forecast period under product types. The product obtains high reactivity and water solubility by calcining magnesite at lower temperatures than dead-burned magnesia. The unique chemical properties of caustic calcined magnesia (CCM) include high reactivity, excellent neutralization capabilities, and suitability for various industrial applications. The chemical and pharmaceutical industries are among the key users of CCM for pH regulation, wastewater treatment, fertilizer, and medicinal formulations. It is also used in agriculture as a soil conditioner and environmental management for flue gas desulfurization and effluent treatment. Its acid-neutralizing capabilities and pH stabilization make it the preferred material in all these processes.
"Synthetic segment is likely to hold a commendable share of the magnesium oxide (MgO) market in 2025"
The synthetic magnesium oxide is anticipated to hold the second-largest share of the global magnesium oxide (MgO) market in 2025. Synthetic magnesium oxide is prepared by chemically precipitating various magnesium compounds, such as magnesium hydroxide or magnesium chloride, which is then calcined to obtain high-purity and controlled-grade magnesium oxide. Due to uniform composition, high purity, and tailor-made reactivity, it is the best alternative wherever natural sources do not generally meet the stringent specifications. Due to its high reactivity and consistency in quality, synthetic magnesium oxide finds application in chemical processing, pharmaceuticals, and state-of-the-art battery technologies. It is also beneficial in environmental management, such as treating wastewater and flue gas desulfurization, where acidic compounds must be neutralized. Synthetic magnesium oxide is also gaining prominence in industries such as electronics, ceramics, and specialty coatings, which require exact performance characteristics.
Magnezit Group (Russia), RHI Magnesita (Austria), Martin Marietta Magnesia Specialties (US), Grecian Magnesite (Greece), and Haicheng Guangling Refractory Manufacturing Co.
