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!
