HPA is generally defined as alumina with purities greater than 99.99% (4N).
Through work at our Technology Development Centre (TDC), we customize our HPA product portfolio to match requirements for specific market applications. Alumina comes in different crystal forms, the most dominant, in terms of application, are alpha and gamma. Gamma HPA is highly porous and used predominantly in catalytic applications. Alpha HPA is used for sapphire-based applications, coatings, ceramics and lithium-ion battery (LIB) separators, and is the form Orbite will be producing initially.
