HPA in Batteries

HPA is a key component in Lithium-ion batteries, improving their performance, reliability and safety. HPA coated separators allow for safer, thermally stable batteries. With HPA purity critical for safe, long life batteries, HPA are a key enabler of the e-mobility and energy storage revolution. One of the most exciting uses of Lithium-ion batteries is in battery electric vehicles—the electric vehicle revolution is one of the key drivers for HPA demand globally.

HPA for Synthetic Sapphire

Synthetic Sapphire is used in scratch resistant glass for premium optics, on premium wristwatch faces , Smartphone camera lenses and LED substrates. HPA is the critical, primary ingredient for synthetic sapphire, sought after for its extreme hardness, its ability to transmit in UV, visible and infrared wavelengths, and for its high heat resistance and thermal conductivity. As in the battery sector, HPA is in demand for its chemical inertness and high electrical resistance. In the production of synthetic sapphire, there is no substitute for HPA.

  • Lenses & Glass
    High end photographic lenses and scratch resistant glass screen protectors are produced from synthetic sapphire
  • Camera Lights
    Synthetic sapphire is used in the production of optical lenses for photography, including Smartphone cameras
  • Watch Face
    Luxury Swiss wristwatches and Smartwatches are made using synthetic sapphire for the face

HPA in LED Lighting

High purity alumina is critical to the production of LED lighting systems. Synthetic sapphire wafer substrates made from HPA are an essential component of LED lights and relied upon for its ultra-pure surface and exceptional thermal conductivity.

Alpha’s Ultra HPA and its Ultra 5N precursors are also key ingredients for the synthesis of LED aluminate phosphors, critical to the down conversion of light to the visible spectrum.

Demand for this greener system of lighting is projected to increase, and demand for HPA is set to follow the same trajectory.

  • Aluminate Phosphors
    Used to down convert blue light to white light
  • GA-N Circuit & Active Layers
    Semiconductor materials as active layers of light emitting diodes
  • Synthetic Sapphire Substrate
    The smooth surface on which the LED is built, offering exceptional thermal conductivity to dissipate heat.
Smart SX Technology

In the world of metals, solvent extraction is not new. However solvent extraction has never been successfully applied to aluminium—until now.

The unique Smart SX Technology is a highly selective scientific process, extracting aluminium with pinpoint accuracy. It gives us the flexibility to generate our ultra high purity aluminium products at a very low carbon footprint.

Smart SX Technology is low impact, in that it recycles its reagents into a saleable by-product, on a 100% basis. While this translates into a cost advantage, the bigger story is the green credentials earned through ingenuity. From here in Australia, we can deliver the world’s most sustainable HPA, aluminium precursors and boehmite to the global markets driving decarbonisation. That’s something we’re proud of.

Our Smart SX Technology Process
About HPA

In its purest form (>99.9% purity), aluminium oxide (Al2O3) is known as high purity alumina—or HPA. The high value of this product is derived from its physical properties: excellent thermal conductivity, extreme hardness combined with chemical stability. These features make HPA a critical ingredient in the manufacture of Lithium-ion Batteries, LED lights, scratch-resistant sapphire glass, smartphone components and semiconductor wafers in electronics. Beyond its immeasurable applications, our Ultra HPA Products are made from the most sustainable high purity alumina process technology in the world.

Existing HPA Processing Methods

The standing methods for producing HPA lean on old technology. Under existing processes, HPA production is synthesised from aluminium metal feedstock, or produced from hydrochloric acid leach of kaolin clay. Both of these processes are energy intensive, produce high emissions, and create a significant amount of waste. Not only is this detrimental to the environment, it’s inefficient.

HPA First Project

Gladstone will be the home of our HPA First facility—a city with a strong industrial pedigree and one of the busiest multi-commodity ports in Australia. This will be the global hub from which we commercialise the Smart SX Technology, with a forecast delivery of 10,000 tonnes of HPA equivalent per annum, creating new opportunities for the local community.
