    AI Overview
    Reactive light-burned magnesia (caustic calcined magnesia) is a highly reactive, white amorphous powder produced by calcining magnesite at 700°C–1000°C. It features high surface area (

    m2
    /g
    ), low crystallinity, and high reactivity, making it essential for environmental treatment, cement production, agriculture, and industrial chemical applications. 
    Key Properties & Characteristics 
    • Calcination Temperature: Produced between 700°C and 1000°C, which leaves it highly reactive compared to dead-burned magnesia.
    • Reactivity: High surface area (
      30

      90
      m2
      /g
       or higher) enables rapid hydration and high adsorption capacity.
    • Composition: Typically contains

      %
       MgO.
    • Physical Form: Fine white powder with low bulk density. 
    Key Applications 
    • Environmental Protection: Highly effective for neutralizing acidic wastewater, flue gas desulfurization, and removing heavy metals.
    • Construction/Cement: Used as a key ingredient in magnesium cements (oxychloride/oxysulfate cements) and fireproof insulation materials due to its binding properties.
    • Agriculture & Livestock: Used for producing magnesium fertilizers and as a magnesium source in animal feed.
    • Industrial Processes: Acts as an acid scavenger, vulcanizing agent in rubber/plastics, and in catalyst manufacturing.
