High purity alumina (HPA) is critical to LED production. Demand for LEDs has surged since 2010 and this demand now accounts for over half of the world’s HPA consumption. But HPA is also being used as coating material for separators in lithium ion batteries.
Dr Richard Flook explores the high purity alumina market and the Australian production projects looking to feed the growing demand.
High purity alumina (HPA) which is usually accepted to be aluminium oxide (Al2O3) of greater than or equal to 99.99% purity (4N or 100ppm impurities) has been forecast to have a high growth future . . .
