The Mean Density of Brick (magnesia) is 2563.0 kg/m³

Magnesia Brick

Magnesia brick is a type of refractory brick made primarily from magnesium oxide (MgO). It is widely used in high-temperature industrial applications due to its excellent resistance to heat, chemical corrosion, and thermal shock.

Composition

  • The main component is magnesia (MgO), derived from magnesite ore or seawater.
  • It often contains small amounts of iron, silica, and calcium as impurities.

Properties

  • High Refractoriness: Magnesia bricks can withstand temperatures up to 2,800°F (1,540°C) or higher, making them ideal for extreme heat conditions.
  • Basic Refractory: They are resistant to basic slags (alkaline environments), making them suitable for steelmaking and cement production.
  • Low Thermal Expansion: This property helps reduce cracking under thermal stress.
  • Good Resistance to Chemical Corrosion: Particularly against alkaline substances like lime and basic slags.
  • High Density and Strength: Ensures durability under mechanical stress.

Types

  • Pure Magnesia Bricks: Made almost entirely of MgO.
  • Magnesia-Chrome Bricks: A blend of magnesia and chromium oxide for enhanced resistance to slag.
  • Magnesia-Carbon Bricks: Includes carbon to improve resistance to thermal shock and corrosion.

Applications

  • Magnesia bricks are primarily used in:
  • Steelmaking Furnaces: Such as electric arc furnaces and oxygen converters.
  • Cement Kilns: Lining for rotary kilns due to their resistance to basic conditions.
  • Non-Ferrous Metal Smelting: For environments requiring durability against heat and chemicals.
  • Glass Industry: Lining areas exposed to high temperatures.
  • Refractory Lining: For incinerators, furnaces, and other heat-intensive equipment.

Magnesia bricks are a critical material in industries where extreme heat and corrosive environments are common. Let me know if you need further details on specific properties or production methods!
