Calcined Aluminum Oxide Powder: A Comprehensive Overview
Calcined aluminum oxide powder, also known as calcined alumina, is a refined form of aluminum oxide (Al2O3). It undergoes a process called calcination, which involves heating aluminum hydroxide or other aluminum compounds to temperatures typically exceeding 800 degrees Celsius1. In this article, we’ll explore the key characteristics, production process, and applications of calcined aluminum oxide powder.Get more news about Calcined Aluminum Oxide Powder,you can vist our website!Key Characteristics of Calcined Aluminum Oxide:
Purity: Calcined aluminas are more pure than fused aluminum oxide products (except for fused white aluminum oxide). When milled, they retain the chemistry of the unmilled crude more closely than fused aluminum oxide.
Shape: Calcined alumina grains consist of single platey crystals, whereas fused aluminum oxide grains tend to be fractions of large crystals and blocky in shape. A calcined crystal resembles a six-sided disk with a thickness about one-fifth of its diameter.
Applications: Calcined alumina is commonly used in glass and metal lapping, polishing, and coated abrasive tapes.
Production Process:
Calcination: Aluminum hydroxide or other aluminum compounds are heated to high temperatures, resulting in the transformation into calcined alumina.
Milling: The calcined alumina is milled to achieve the desired particle size and shape.
Applications:
Lapping and Polishing: Calcined alumina is used for precision lapping and polishing of glass and metal surfaces.
Coated Abrasive Tapes: It finds application in coated abrasive tapes for various finishing processes.
Calcined aluminum oxide powder offers superior performance in grinding, blasting, lapping, and polishing applications. Its high purity and unique crystal shape make it an excellent choice for various industrial processes. Remember, when it comes to abrasive grains, expect excellence and accept no substitutes!
