Reactive alumina is a specialized form of aluminum oxide whose properties are controlled to enhance reactivity. It is used in various applications such as catalyst production, chemical processing, and refractories. Reactive alumina is completely milled into primary (single) crystals by highly efficient milling processes, yielding an average particle size, D50, with a monomodal distribution. Reactive alumina is crushed fully calcined alumina in which a significant portion (20 to > 90%) consists of primary crystals smaller than 1 µm. Reactive alumina powder is processed for use as a reactive adhesive in a variety of applications. Reactive grade alumina is designed for high performance due to the uniform and tightly controlled particle size distribution developed [1]. Reactive grades are more stable than calcined alumina and are therefore suitable for dense, high-strength and wear-resistant materials.
Reactive alumina applications
Reactive alumina has various applications in various industries. Here are some applications of reactive alumina:
Production of catalyst
Reactive alumina is used in the manufacture of catalysts due to its increased reactivity.
Refractory products
Reactive grade alumina meets the stringent application requirements of advanced ceramics and high-quality refractories, such as castable refractories. Reactive alumina is specifically designed to produce high performance refractories where particle packing, rheology and consistency are determined.
Chemical treatment
Reactive alumina is used in chemical processing due to its controlled properties to improve reactivity.
Structural ceramics
Reactive grade alumina powder is processed for use as a reactive binder in many applications including technical ceramics and structural ceramics.
Electrochemical anodic oxidation
Alumina has significant potential for many applications, including electrochemical anodic oxidation.
