Magnesia brick is a type of refractory brick made primarily from magnesia, a mineral composed of magnesium oxide (MgO). The properties of magnesia brick include:
1.High temperature stability: Magnesia bricks have excellent resistance to high temperatures and can withstand temperatures above 1700°C.
2.Good corrosion resistance: Magnesia bricks have good resistance to the attack of basic slags, which makes them suitable for use in furnaces where basic slag conditions exist.
3.High refractoriness under load: Magnesia bricks maintain their strength and dimensional stability at high temperatures, even under heavy loads.
4.Low thermal expansion coefficient: The low thermal expansion coefficient of magnesia bricks helps to reduce the risk of cracking or deformation due to sudden changes in temperature.
Good thermal conductivity: Magnesia bricks are good conductors of heat, allowing them to transfer heat quickly and efficiently to where it is needed.
-
Excellent electrical insulation: Magnesia bricks are good electrical insulators, making them ideal for use in electrically heated furnaces.
-
High compressive strength: Magnesia bricks have high compressive strength, which enables them to resist high mechanical stresses.
-
Low porosity: Magnesia bricks have a low porosity, which makes them resistant to the penetration of molten metals and slags.
Overall, the properties of magnesia brick make it an ideal material for use in furnaces and other high-temperature applications, especially those involving basic slags.
