What is Caustic Calcined Magnesite Powder
What is Caustic Calcined Magnesite Powder？
Caustic Calcined Magnesite Powder, also known as Light-Burned Magnesia or Caustic Calcined Magnesia, is a highly reactive magnesium oxide (MgO) powder. It is produced by calcining natural magnesite ore at controlled temperatures between 800°C to 1000°C. This process drives off carbon dioxide, resulting in a porous, lightweight powder with significant chemical activity and a large surface area. It serves as a crucial raw material for numerous industrial applications and is a key intermediate product for manufacturing higher-grade magnesia products.
Core features of the product
High Chemical Reactivity: Its porous structure and lattice defects grant it excellent reactivity, making it highly effective in chemical processes and as a binding agent.
Strong Binding Properties: When mixed with water, it hydrates to form a cementitious bond, which is fundamental in the production of magnesia cement and related construction materials.
Versatile Neutralizing Agent: Its alkaline nature makes it an efficient and cost-effective acid scavenger for environmental and industrial processes.
Excellent Refractoriness Precursor: It is the essential starting material for producing Dead Burned Magnesia (DBM) and Fused Magnesia, which are critical for high-temperature refractory linings.

Application
Caustic Calcined Magnesite is a versatile material prized for its reactivity and bindingConstruction & Building Materials: The largest application area. It is the core
• Construction & Building Materials: The largest application area. It is the core component of Magnesium Oxychloride (Sorel) Cement, used to produce fireproof boards, lightweight partition walls, floor underlayments, and decorative panels due to its fast setting, high strength, and fire resistance.
• Environmental Protection: Used in Flue Gas Desulfurization (FGD) to neutralize acidic sulfur dioxide (SO₂) emissions from power plants and industrial boilers. It is also effective in wastewater treatment for pH adjustment and heavy metal removal.
• Agriculture: Serves as a magnesium nutrient supplement in fertilizers to correct soil magnesium deficiency. Also used as a carrier for other nutrients and as a feed additive for animals.
• Metallurgy: Employed as a sintering agent in iron ore pelletizing and as a binding agent for refractories. It is also used in steelmaking as a slag coagulant and for furnace lining maintenance.
• Chemical Industry: A key raw material for producing various magnesium chemicals, including Magnesium Sulfate, Magnesium Hydroxide, and other magnesium salts. properties. Its primary applications span several key industries

FAQ
1.What is the main difference between Caustic Calcined and Dead Burned Magnesia?
The key difference lies in their calcination temperature and resultant properties. Caustic Calcined Magnesia is fired at 800-1000°C, making it chemically reactive and porous. Dead Burned Magnesia is sintered at much higher temperatures (above 1500°C), resulting in a dense, crystalline, and inert product with excellent volume stability at extreme temperatures, primarily used in refractories.
2. How do I choose the right MgO content grade for my application?
For high-strength magnesium cement boards, grades with MgO ≥92% and controlled reactivity are critical.
For environmental scrubbing (e.g., desulfurization), grades with MgO 85-90% offer an optimal balance of effectiveness and cost.
As a precursor for refractories, the chemical purity (SiO₂, CaO, Fe₂O₃ content) is as important as the MgO percentage to ensure the performance of the final sintered product. Our technical team can help you select the most cost-effective grade.
