Product Description

 

Product Description

Product Description
Phosphate Bonded High Alumina Bricks are refractory materials primarily composed of high-alumina raw materials (e.g., bauxite) bonded with phosphate-based binders. They exhibit high refractoriness, excellent mechanical strength, and thermal shock resistance due to their dense structure and chemical stability under high temperatures. These bricks are characterized by low porosity and enhanced resistance to abrasion and slag corrosion.
Key Features
High alumina content (typically ≥75% Al2O2) ensures superior heat resistance.
Phosphate bonding enhances structural integrity and adhesion at elevated temperatures.
Good thermal shock stability and load-bearing capacity.

Applications
Widely used in cement kilns, rotary furnaces, and industrial kilns requiring high-temperature resistance.
Suitable for lining high-wear zones in metallurgical and chemical processing equipment.
Applied in environments demanding resistance to alkaline or acidic slags.
