Alpha HPA's ultra-high purity aluminium is redefining the landscape and standard of HPA with a range of products designed to meet the demands of modern industries. Our portfolio of products is tailored to enable breakthroughs in electronics, energy storage, and advanced manufacturing by delivering consistent quality, exceptional performance with up to ~70 percent lower carbon emissions.
One of our core products – Ultra-High Purity Alumina(Al2O3) Powder TM, has a remarkable >99.95% (4N5) purity. This finely engineered material is available in both alpha and gamma phases, customised to meet specific customer requirements. With bespoke particle sizing and precise surface area (BET) options, it’s a reliable choice for applications requiring precision, such as LED substrates and phosphors.
Alpha HPA’s Process Support Engineer Matt Millar says, “the engineering of ultra-high purity alumina is a fine balance of thermodynamic control and precise material synthesis.”
“At Alpha HPA, our process optimisation ensures that every product, whether it’s finely engineered ultra-high purity nano-powder TM or ultra-high purity alumina tabletsTM, meets stringent specifications for phase stability and surface morphology.”
“The exceptional purity levels we achieve, are not just a measure of quality, but a result of careful manipulation of reaction conditions and advanced purification techniques.”
Building on this, our ultra-high purity alumina tabletsTM are critical feedstock for synthetic sapphire growth. These high-density, sintered tablets, tailored to bespoke shapes, support flawless synthetic sapphire production, enabling advanced applications in optics, smartphone screens, and semiconductors. This innovation is part of our Alpha Sapphire product line.
For cutting-edge industries requiring nano-scale precision, our ultra-high purity nano-powder TM is engineered into primary particle sizes as small as 50nm and a purity of >99.99% (4N), this alpha-phase material excels in chemical mechanical planarisation (CMP) slurries and LED nanophosphors. It’s a standout for its ability to achieve exceptional polishing and light-emitting performance.
Our 5N Ultra Aluminium NitrateTM nitrate takes purity to the next level with >99.999% (5N) quality, available as both crystals and solutions. This material is indispensable for coating lithium-ion battery electrodes, producing YAG laser crystals, and enhancing CMP slurry oxidants. Its exceptional purity ensures it meets the stringent requirements of optoelectronics and advanced battery technologies.
For battery innovators, our 5N Ultra Aluminium SulfateTM offers premium quality for synthesising lithium-ion cathode materials. Designed to optimise performance in NCA, NCMA and NMA battery chemistries, it enhances energy density and longevity, making it a vital component for next-generation energy storage solutions.
Our portfolio of products also includes a 5N Ultra-High Purity Alumina Tri-HydrateTM, a world leading material in its class. This ultra-pure hydrate is used for creating high-performance ceramics and other advanced materials, thanks to its unparalleled purity and reliability. The unique properties of our ATH make it an ideal material for Direct Lithium Extraction (DLE) applications, enhancing the efficiency and effectiveness of lithium extraction processes.
“The company has now received further encouraging test work results from end users, where Alpha’s materials are showing benefits across a range of additional technical performance metrics, including lithium extraction rates,” Mr. Millar explains.
Finally, our low-carbon synthetic Ultra SapphireTM, produced from ultra-high-purity aluminium tablets, is setting new benchmarks in sustainability and quality. These bespoke sapphire shapes are pivotal in industries like optics and electronics, offering precision and reduced environmental impact.
Alpha HPA’s comprehensive suite of ultra-pure materials supports a variety of industries in achieving precise, reliable and sustainable outcomes. Our products are used in sectors such as renewable energy, electronics and advanced manufacturing, providing the high-purity consistency necessary for these critical applications. With a focus on meeting the specific needs of our customers, we aim to contribute to the ongoing advancements in these fields.
