The product is generally extracted using the Bayer process, which involves the dissolving of bauxite-based minerals by using caustic soda, followed by the product’s chemical isolation. HPA products display high brightness characteristics which make them a popular choice for various applications like the development of energy-efficient and eco-friendly lighting solutions, particularly for advertising displays.
The 4N HPA products with 99.99% purity are commonly implemented as separators in lithium-ion batteries which are used to power electric vehicles and electronic devices. Innovations in the technological landscape in tandem with the sustainable-energy wave sweeping across the globe has augmented the acceptance of electric vehicles. This proves beneficial for the global high purity alumina market scenario, as the product is widely used in the control of air and fuel mixture automobile engines with high heat conductivity owing to its high electrical insulation capabilities.
Additionally, HPA is also frequently used in creating catalytic filters to combat the dust produced from the combustion of diesel in engines. These factors coupled with the rising need for heavy vehicles and passenger cars across emerging economies are likely to boost the auto industry to a great extent, in turn bolstering HPA market outlook in air-to-fuel sensors.
High purity alumina is being used extensively in the production of synthetic gemstones, particularly sapphire, as a base product in the generation of sapphire substrates, which will considerably propel industry growth in years to come. Synthetic sapphires, considered to be equivalent to natural sapphires are obtained through a flame fusion process, also called the verneuil process, which uses high purity alumina powder in the synthetic gemstone production process.
The 5N HPA segment is expected to register revenue of over $1 billion over 2025, given its widespread usage electrolytic capacitator foils, electronic storage systems, photovoltaic cells and sapphire substrates.
In terms of revenue, the high purity alumina market from the 4N HPA sector is anticipated to record remuneration of nearly $2.5 billion over 2025. Even back in 2017, 4N segment held over 70% of the high purity alumina market share. This growth may be attributed to its proliferating application in myriad sectors like eco-friendly lighting solutions as well as for abrasive and sapphire-single crystals.
High corrosion and breakdown resistance, brightness and elevated hardness levels are factors which make high purity alumina the preferred precursor for the production of artificial sapphire and rubies. Additional applications include watch covers, advertising displays, residential lighting, cell phones and fiber optic communication systems, among others.
The high purity alumina market share from phosphor segment is expected to be pegged at over $550 million by 2025. the surge in demand for phosphor-based products like plasma televisions is likely to strengthen the high purity alumina business landscape, owing its use in controlling the properties of phosphorous products.
