Today’s market size shows the total global revenues for high purity alumina (HPA) in 2018, 2020, and projected for 2025.1 HPA is a high purity form of aluminum oxide (Al2O3). It is an essential ingredient in the production of synthetic sapphire. Synthetic sapphire is used in the manufacture of substrates for LED lights, semiconductor wafers, and scratch-resistant sapphire glass for wristwatch faces, optical windows, and smartphones. HPA is also used to manufacture bio-medical devices such as pacemakers, intraocular cataract lenses, vascular grafts, orthopedic pins, and surgical tools. As a coating, it is used on the separator sheets in lithium-ion batteries.

In 2018, global demand reached 19,000 tons per annum (TPA). By some estimates, demand will reach 272,000 TPA in 2028. Growth in the HPA market will primarily be driven by demand for LED lighting and electric vehicles. In 2018, LED lighting garnered about half of the HPA market. Growth will come from government incentives for the installation of energy-efficient lighting, declining prices, consumer demand for environmentally-friendly lighting alternatives, and the increased usage of LED lighting in automotive manufacturing. In 2020, electric vehicles accounted for 4.2% of light vehicle sales worldwide, almost double the percentage in 2019. Thirteen countries saw electric vehicle sales of greater than 10% of all passenger cars sold. Thanks to tax exemptions, toll exemptions, and other incentives nearly 75% of all passenger car sales in Norway in 2020 were for electric vehicles. By unit sales, China led with 1.3 million plug-in electric vehicles sold in 2020, a 15% jump from the year before. Some countries such as Germany, France, and the United Kingdom had triple-digit sales growth over this time. With battery costs dropping 90% over the last 10 years, more than 600 electric vehicle models launching by 2025, and governments worldwide mandating transitions to clean fleets by 2030 or 2050, the World Economic Forum predicts that by 2040, half of all new vehicles sold will be electric.

HPA comes in three grades. 4N is 99.99% pure. It’s commonly used in LEDs, energy storage capacitors, lithium-ion batteries, and decorative and bright finishes. In 2018, this grade of HPA constituted about 64% of sales.2 5N is 99.999% pure and is used in liquid crystal displays and in thin-film applications in the semiconductor industry. Because of its scratch resistance, chemical stability, and extreme hardness, it, along with 4N, is used in synthetic sapphire production. 6N is 99.9999% pure and is the most expensive grade of HPA. It’s used in semiconductors, solid-state lasers, sensors, abrasives, alumina ceramics, and separator membranes. 6N is expected to see significant growth as demand increases from the aerospace and defense, automotive, health care, and electronics industries.

By region, the Asia-Pacific region had a 67.3% revenue share in 2018, with China, Japan, and Australia being the major markets. All have been expanding manufacturing capacity to meet the demand for LEDs, lithium-ion batteries, and smartphones at home and elsewhere. Europe and North America are each expected to experience a greater than 14% compound annual growth rate through 2025 as demand for lithium-ion batteries in Europe and LEDs in both regions grows significantly. There are a small number of major producers operating globally. These include Sumitomo Chemical Co. Ltd., Sasol Ltd., Baikowski SAS, Hebei Heng Bo New Material Technology Co. Ltd., Nippon Light Metal Co. Ltd., Altech Chemicals Ltd., and Polar Sapphire Ltd.
