Caustic Calcined Magnesia Market Size, Share & Industry Analysis, By Application (Agricultural, Industrial, Chemical, Construction, Environmental, Steel / Refractories, Cosmetics, Others) And Regional Forecast, 2026-2034

The global caustic calcined magnesia market size was valued at USD 25.67 billion in 2025. The market is projected to grow from USD 28.3 billion in 2026 to USD 61.71 billion by 2034, exhibiting a CAGR of 10.24% during the forecast period.

The caustic calcined magnesia also called light calcined magnesite. It is a highly reactive form of magnesium oxide and manufactured by burning naturally occurring magnesium carbonate (magnesite) at temperatures between 800-1500 ° C. It appears as a white or yellow color and available in the powder form.  The caustic calcined magnesia is available in different types of purity and particle sizes, which makes it suitable in the wide range of applications. Additionally, the reactivity, purity level, and surface area surge the demand for caustic calcined magnesia in the agricultural, industrial, chemical, construction, environmental, steel, refractories, and cosmetics applications.

The caustic calcined magnesia is used as a raw material for the production of magnesite ball. At high pressure, the caustic calcined magnesia is mixed with water and binder to produce the balls. The magnesite balls are further used to form an effective protective layer of slag on the furnace lining and as a protective slag of converter slag splashing composition regulator. Moreover, in the environmental applications, the caustic calcined magnesia is utilized in the soil decontamination, waste neutralization, water treatment, and flue gas treatment. Hence, rising demand for the product from environmental applications will fuel market growth during the forecast period.

However, the high demand for caustic calcined magnesia from a wide range of applications causes unavailability. This further restricts its adoption in various applications.
