Refractory cement

Improved fire resistance:

Magnesia has a melting point of up to 2800°C, which makes magnesia cement have excellent fire resistance at high temperatures. 

In metallurgy, glass, petrochemical and other high-temperature industries, magnesia cement can be used for a long time, 

providing stable thermal protection and extending the service life of equipment.

Increase mechanical strength:

Magnesium-based refractory has excellent heat resistance and thermal shock resistance, and can be used in high temperature furnace 

for a long time to provide stable thermal protection. The addition of magnesia significantly improves the mechanical strength of cement, 

including compressive strength and flexural strength.

Improved corrosion resistance:

Magnesium oxide has strong anti-erosion ability to alkaline metal solution, so that magnesium oxide cement can maintain stable performance in 

the corrosive environment of strong alkali metal. This characteristic makes magnesia cement widely used in chemical and smelting industries.

Reduce thermal conductivity:

The addition of magnesia can reduce the thermal conductivity of cement and improve its thermal insulation performance. 

This is important for applications where insulation is required, such as building facades and thermal insulation in high-temperature furnaces.

Improved dimensional stability:

In the sintering process, the coefficient of thermal expansion of magnesium oxide is low, which helpto maintain the 

dimensional stability of the cement. This makes the cement less prone to deformation during high temperature and cooling, 

ensuring the precise size of the product and good assembly performance.
