Applications
Phosphate bonded high alumina bricks are widely used in high-temperature industrial applications, including cement rotary kilns (transition zone, preheat zone, and cooler lining), lime kilns, and rotary kilns for metallurgical solid waste and magnesium production. They are also suitable for steel and non-ferrous metal smelting, as well as ceramics, glass, petroleum, chemical, and power industries.
