High Purity Alumina Market to Touch $10 billion by 2030, LEDs & Li-ion Batteries Propel the Demand

 

Introduction

High Purity Alumina (HPA) is a highly refined form of aluminum oxide (Al2O3), characterized by purity levels of 99.99% (4N), 99.999% (5N), and 99.9999% (6N). Its unique properties, including thermal stability, high corrosion resistance, and exceptional hardness, make it a crucial material in various high-tech applications.

Production Technologies Enhancing HPA Quality

HPA is synthesized using advanced chemical techniques such as hydrolysis of aluminum alkoxide and hydrochloric acid leaching. These methods effectively remove impurities like sodium, iron, and silicon, ensuring the desired purity levels. Compared to traditional energy-intensive processes like the Bayer process, hydrochloric acid leaching and direct extraction from kaolin clay have emerged as eco-friendly and cost-efficient alternatives.
