The high purity alumina market is driven by LED industry growth and Asia Pacific's manufacturing boom, with significant demand for 4N and 5N grades.
Plummeting costs of LEDs and increasing consumer shift towards replacing incandescent lights with LED lights, owing to their high energy efficiency and low carbon emissions is in turn expected to create highly lucrative growth prospects for the global high purity alumina market throughout the forecast period (2017–2025). Artificial sapphire is used as a substrate in production of LEDs, onto which the emitting layer of the LED is deposited as a vapor. Artificial sapphire is derived from high purity alumina by single crystal technology. As per stats released by Coherent Market Insights, the 4N purity segment was pegged at US$ 744 million in 2016. 99.99% purity level the 4N grade alumina is widely used, due to easier availability of smelter grade and low production cost. The 4N grade high purity alumina is widely used in gas separation and ultra-filtration process due to its high chemical resistance, porous nature, and mechanical strength. Moreover, demand for 5N grade high purity alumina is expected to witness significant growth during the forecast period as it finds wide application in scratch-proof sapphire glass and high end electronic displays. The market is expected to gain traction in Asia Pacific region due to burgeoning growth of various end-use industries in China, Taiwan, South Korea and India.
Asia Pacific has emerged as a major manufacturing hub, with major players focusing on capitalizing on economies of scale in the region. Furthermore, the region is a highly lucrative market for consumer electronic products, on the back of rampant economic growth in countries such as India and China. Besides, as per statistics released by India Brand Equity Foundation (IBEF)—a trust established by the Department of Commerce, Ministry of Commerce and Industry, Government of India—the country is poised to emerge as the second-largest market for smartphones in 2017. According to stats released by Coherent Market Insights, the electronic display market is projected to exhibit a robust CAGR of 16.9% during 2017-2025. These factors collectively position Asia Pacific as a powerhouse in the global high purity alumina market, and is expected to retain its dominance in the market through 2025.
Top Key Players in High purity alumina market: Altech Chemicals Limited, Nippon Light Metal, Baikowski Pure Solutions, Polar Sapphire Ltd., Orbite Technologies Inc., Sumitomo Chemical Co. Ltd., and Alcoa Inc.
This report segments the global high purity alumina market on the basis of purity level, application, and technology. On the basis of purity level, the market is segmented as 4N, 5N and 6N. On the basis of application, the global high purity alumina market is segmented as semiconductor, phosphorus, electronic display and sapphire. On the basis of technology, the global high purity alumina market is segmented into hydrolysis and HCL based.
Aluminum oxide or alumina, commonly known as AL2O3, is the primary raw material used for the manufacturing of metallic aluminum. Moreover, 90% of alumina used in aluminum metal production is known as Smelter Grade Alumina (SGA) and remaining 10% is used in non-metallurgical industry for chemical or specialty use. High Purity Alumina (HPA) is one of the purest forms of aluminum oxide. HPA is widely used in various end use industry such as LED and semiconductor manufacturing industries. Furthermore, the artificial sapphire substrates found in LED, scratch proof artificial sapphire glass, semiconductors are primarily made from HPA. 99.99% purity HPA, (4N) Al2O3, is the high end and high value product of non-metallurgical industry.
High purity alumina is a highly capital intensive market, which makes it difficult for new players to enter into the market. The cost of end products will be high and profitability will be low if the production costs are high. Therefore, the market is highly consolidated and the, market is dominated by major players based in Australia and China due to large bauxite reserves, which is the basic raw material required for the production of high purity alumina, in these economies.
