Alumina (aluminium oxide) is a white granular material produced from the refining of bauxite. Around 90 per cent of the world's alumina is smelted to produce aluminium metal. Around two tonnes of alumina is required to produce one tonne of aluminium.
Alumina is the common name given to aluminum oxide (Al2O3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions.
Only about 10% of alumina is used in non-metallurgical application and is known as high purity alumina. High-purity alumina contains a minimum of 99.99% pure aluminium and is a type of non-metallurgical alumina.
High Purity Alumina Market is expected to garner $5,293 million by 2023, registering a CAGR of 17.0% during the forecast period 2017-2023. The market for high purity alumina has witnessed tremendous growth during the past few years and is expected to grow at a CAGR of 20.7% in terms of volume, during the analysis period. World demand for high purity alumina has gained an incredible traction, owing to growing technological advancements and increasing demand from applications namely LED bulbs, electronic displays, automotive and medical. This trend is expected to continue with growing adoption of HPA by end users and emerging technological advancements in electronics industry. Increasing penetration of LEDs in the lighting market, newer applications of high purity alumina in smartphones, smartwatches and tablets, are significant factors driving the growth of the high purity alumina market. However, higher cost of production is expected to impede the high purity alumina market growth.
