Caustic Calcined Magnesite (CCM) and Light Burned Magnesia (LBM) are two magnesium oxide (MgO) products that have been processed by different calcination processes. Although they are similar in composition, they have significant differences in production process, physical properties and application fields.
1. Calcination temperature and process
The calcination temperature range of Light Burned Magnesia may be lower (such as 750–900°C), and it has a higher specific surface area and porosity.
2. Physical and chemical properties
Light Burned Magnesia is highly active, with a small and loose crystal structure. The specific surface area is usually 100–200 m²/g, depending on the calcination parameters.
3. Application areas
Light Burned Magnesia is more widely used in Magnesium-based chemicals, building materials, magnesium cement, fireproof boards, thermal insulation materials, and acidic wastewater treatment.
Steel: steelmaking desulfurizer, magnesia refractory bricks, castables, gunning materials
Glass: glass melting furnace refractory materials, improving glass alkali resistance
Cement: refractory lining, alkaline regulator
Environmental protection: wastewater treatment, flue gas desulfurization (FGD)
Agriculture: soil conditioner, animal feed additives
Chemicals: production of magnesium oxide slurry, magnesium compounds (such as magnesium hydroxide, magnesium sulfate, magnesium chloride)
Building materials: manufacturing magnesium cement (Sorel Cement), magnesium board, fireproof board
Environmental protection: sewage treatment, flue gas desulfurization
Medicine and food: pharmaceutical grade magnesium oxide, food additives
