Reactive grade aluminas meet the stringent application requirements of advance ceramics and high-quality refractory products, such as castable refractories. AluChem’s reactive grade aluminas are designed for a high-level of performance due to tightly controlled and homogenized particle size distributions developed around high-purity alumina milling components. These finely milled products are controlled to a specific surface area and green density to optimize fired density and provide for controlled shrinkage. Reactive grade products offer excellent sinter reactivity, reduced water demand, and enhance the final product in terms of porosity, wear resistance, mechanical strength and high-temperature mechanical performance.
