High Purity Alumina

HIGH PURITY ALUMINA

High-purity alumina (HPA) is a processed premium non-metallurgical alumina product characterised by its purity level – i.e. 99.99% (4N) or 99.999% (5N). The market price, application and performance of HPA varies widely according to its degree of purity.

HPA is used because of its superior properties and characteristics, such as excellent corrosion and scratch resistance, high brightness, and its ability to withstand extreme temperatures. It is used as a base material in the manufacture of sapphire substrates for applications such as light emitting diodes (LEDs), in the manufacture of artificial sapphire glass (eg mobile phone and television screens) and in certain battery and power storage components, artificial gemstones and special space, aeronautical and medical applications.

HPA is increasingly becoming the primary sought-after input material for certain high-tech products, principally for its unique characteristics and chemical properties that address those applications’ high specification requirements, such as LEDs and other sapphire glass products.

The longer-term driver for HPA, with forecasts of >17% year-on-year growth (GAGR)*, is the outlook for the burgeoning electric vehicle and static energy storage markets where the primary function is in use as a separator material between the anode and cathode in batteries to increase power, functionality and safety of the battery cells.

Developing a long-life,
sustainable HPA project

an emerging high purity alumina producer
utilising its innovative flowsheet design for
high quality, low cost production of HPA

Cadoux Limited has developed an innovative process design for the integrated production of high-quality HPA, predominantly for electric vehicles (lithium-ion batteries), sapphire glass (LED) and broader technology applications. Importantly, Cadoux has positioned and branded its product as premiumHPA®, reflecting its ultra-high purity, consistency and suitability for demanding, high-specification applications.

HPA is increasingly becoming the primary sought-after input material for certain high-tech products, principally for its unique characteristics and chemical properties that address those applications’ stringent requirements, such as LEDs and other sapphire glass products.
