According to a research report published by Spherical Insights and Consulting, the global High Purity Alumina market size was worth around USD 4.72 Billion in 2024 and is predicted to grow to around USD 48.6 Billion by 2035 with a compound annual growth rate (CAGR) of 23.61% from 2025 to 2035. During the projected period, market growth is expected to be driven by the growing usage of high-purity alumina (HPA) in electric vehicle (EV) batteries and components in electronics production.

 

Market Overview

The global high purity alumina market refers to the industry focused on producing aluminum oxide with a higher purity level, widely used in LEDs, lithium-ion batteries, semiconductors, and advanced optical and electronic applications. The market for high purity alumina (HPA) is expanding rapidly because of the growing need for improved electronic components, LED lighting, and batteries for electric vehicles. By increasing discharge resistance and separator stability, HPA, a refined version of aluminium oxide with 99.9% or higher purity (4N–6N), improves the longevity and performance of lithium-ion batteries. It is crucial for the production of LEDs, semiconductors, and synthetic sapphire substrates used in microelectronics because of its exceptional qualities, which include thermal stability, brightness, and hardness. The U.S. Department of Energy predicts that by 2035, LED lighting will be widely adopted, which is expected to accelerate industry growth. Technological developments, such as solvent-extraction techniques and hydrochloric acid leaching, are lowering production costs and emissions, promoting sustainable growth.

 

The market potential is further strengthened by the increasing usage of ultra-high purity grades in patterned sapphire substrates, vertical GaN devices, and EV batteries. Further investment and innovation in the HPA sector. In 2019, Altech Chemicals produced HPA from its kaolin clay deposit using a particular method. Additionally, Altech is investigating the use of HPA in the production of epoxy moulding compounds, which are utilized in the semiconductor sector to enhance heat dissipation.
