ZA25 0-1MM 1-3MM 3-5MM For refractory

 

Description:

Zirconia fused alumina with ZrO2 22-26% content is a good refractory material for making corundum refractory bricks and ladle components. The most distinct advantage of Zirconia fused alumina is high roughness and durability. ZA25 fractions can be resistant to thermal impact. So ZA base firebrick works excellently in the glass furnace and kiln.

 

 

ZA25 0-1MM 1-3MM 3-5MM For refractory Characteristic:

1.    High refractoriness and thermal resistance to melting erosion.

2.    Excellent wear resistance for its small crystal size at 10-20um.

3.    Wear resistance to heavy duty load.
