The global high purity alumina (HPA) market was valued at USD 1.73 Billion in 2014, and is projected to reach USD 5.09 Billion by 2020, at a CAGR of 20.1% from 2015 to 2020. Increase in demand of HPA in varied applications, such as LED, semiconductor, phosphor, and sapphire, among others is fueling the growth of this market.

Among all applications, the LED segment led the high purity alumina market in 2014. More than half of the production of high purity alumina is used in lighting, automobile headlights, and mobile phones backlights, among others.

The shift from traditional incandescent light bulbs to energy-efficient and sustainable LED lighting systems has helped in increasing the overall demand for LEDs. The growing usage of LED lighting by both developed and emerging countries is projected to drive the demand for LED application segment in the high purity alumina market.

On the basis of purity level, the high purity alumina market is segmented into 4N, 5N, and 6N. 4N high purity alumina serves to be the main source material used in the development of scratch-resistant artificial sapphire glass. They are also utilized in smartphones and portable tablet devices.

The price of HPA depends on its impurity profile (that is, the content of silica and iron), product type (powder, block, cake, seed, pellets, ball, and ingot), and product characteristics (particle size and density). HPA prices are expected to decrease owing to its increased supply from small producers in China.

Asia-Pacific held the largest share in the global high purity alumina market in 2014. The high purity alumina market in the Asia-Pacific region is projected to grow at the highest CAGR during the forecast period. China dominates the HPA market in the Asia-Pacific region, owing to technological advancements made in the electronics sector in this country.

Expansions, new product/technology launches, joint ventures, agreements, and acquisitions are some of the most essential strategies adopted by key market players to achieve growth in the global high purity alumina market. Companies such as Altech Chemicals Limited (Australia), Alcoa Inc. (New York), Orbite Technologies Inc. (Canada), Sumitomo Chemical Co., Ltd. (Japan), and Bukowski (France) are actively present in the high purity alumina market.
