High purity alumina is extensively used for non-metallurgical applications and is a highly purified form of aluminum oxide. The product finds extensive application in sapphire substrate manufacturing. Sapphire substrates are preferable window materials owing to their superior chemical and mechanical characteristics, including resistance to thermal shock, high temperature, minor dielectric loss, and sand & water erosion, among others. Additionally, it finds wide application in products like plasma display screens, LED lights, smartwatches, smartphones, li-ion battery separators, optical lenses, sodium lamps, semiconductors, electric & hybrid vehicles.

Furthermore, the high penetration of light-emitting diodes into the market and increasing demand for LED bulbs is significantly fueling the high purity alumina consumption. The superior characteristics of LEDs, such as adequate brightness, reliability, nominal heat radiation, and high durability are some of the factors attributing to the market expansion. Additionally, the lightning sector has observed some tremendous growth over the past decade due to the augment of light-emitting diodes (LEDs) in the market. Rising construction activities, favorable government norms for energy-efficient products, and other macroeconomic factors have substantially contributed to the increased number of new LED installations.

On the other hand, the production of high purity alumina involves high costs that may present challenges to manufacturers and hamper the growth. Besides, the market supply chain was severely disrupted on account of the outbreak of COVID-19 disease. The market witnessed a downfall of over 1.5% in 2020, however, it is anticipated to regain the previous growth rate in the approaching years.

The hydrolysis segment accounted for over 65% of the North America high purity alumina market share in 2020 due to its high feasibility compared to other methods for producing high purity alumina (HPA). The process includes the addition of alcohol into aluminum metal, which produces alumina. Later, high purity alumina is obtained by the calcination procedure. The acid that is used during the process is recoverable and can be used re-used. This leads to alleviated operational costs and renders hydrolysis to be a more economical method for HPA synthesis.
