Magnesia Zirconium Brick For Furnace Regenerator
Magnesia Zirconium Brick For Furnace Regenerator

Minimum Order: 0
Quality/Safety Certification: 0.00


1. High alkali-resistance
2. Well thermal stability
3. Good heat conductivity
4. High softening temperature

Features:

Magnesia zirconium brick chooses high quality magnesia sand and zircon as raw material and is made by middle,high temperature firing. Compared with other magnesia bricks, it has the following advantages:

1.Well thermal stability 

 2.Good heat conductivity.

3.High softening temperature

4.Superior alkali-resistance and repeated evaporation-condensation resistance.

 

Application:

Widely used as the regenerator middle and upper refractory material for heat exchange.
