Fused zirconia mullite refractory bricks have high refractoriness and corrosion resistance. Fused zirconia mullite bricks can withstand high temperatures, high pressures and highly corrosive environments.
Fused zirconia mullite bricks are high quality refractory bricks composed of two main components, alumina (Al2O3) and zirconia (ZrO2), with zirconia content generally ranging from 30% to 50%. Fused zirconia mullite refractory bricks have high refractory and corrosion resistance and can withstand high temperatures, high pressures and highly corrosive environments.
High hardness
Fused zirconium mullite refractory bricks have a high degree of hardness and are resistant to abrasion and scratches.
High strength
Fused zirconia mullite bricks have high strength and can withstand high loads and pressures.
Corrosion resistance
Fused cast zirconia mullite firebricks are highly resistant to acid, alkali and other corrosive substances.
High temperature resistance
Fused zirconia mullite bricks can withstand high temperatures and will not be deformed or damaged due to high temperatures.
Aesthetics
The surface of fused zirconia mullite bricks is smooth, delicate and even with rich color, which has good decorative effect.
Good durability
Fused zirconium mullite firebricks are not easy to aging, fading and deformation, and have a long service life.
Good safety
Fused Zirconia Mullite refractory bricks are not easy to burn and explode, which is conducive to ensuring the safety of buildings.
Environmentally friendly
Fused zirconia mullite bricks do not contain harmful substances, no pollution to the environment, is a kind of green building materials.
Chemical and metallurgical industry kilns subject to solution erosion parts
Fused zirconia mullite bricks are widely used in high temperature furnaces, crucibles and heat preservation bricks in metallurgical industry, such as iron and steel furnace linings, iron furnace linings, electric furnace linings and so on. They have good resistance to high temperature, corrosion and thermal shock, can withstand high temperature metal liquids and high temperature gas erosion, is the manufacture of chemical industry, metallurgical industry kiln lining of high quality materials.
Picture tube kiln
Fused zirconium mullite firebricks have excellent thermal shock resistance and high-temperature strength, and are able to withstand high temperatures and high stresses, making them ideal for the lining of picture tube kilns.
Heat storage room partition brick
Fused zirconium mullite refractory bricks have excellent thermal shock resistance and high-temperature strength, can withstand high temperatures and high stress, is the ideal material for manufacturing heat storage room partition wall bricks.
