Introduction
Aluminum Oxide, or Alumina, is a white crystalline chemical substance made mostly from the mineral bauxite. It's utilized in a wide range of advanced applications, such as anti-corrosion materials, wear and abrasion-resistant parts, and the electronics industry. Alumina is a cost-effective material with high quality properties such as high durability, brightness, low heat radiation, and high temperature stability.
The increased usage of aluminum oxide in the manufacture of porous ceramics has had a significant impact on alumina growth. In accordance with this, the rising demand for dental cements as well as industrial manufacturing processes is also operating as a crucial element that will boost alumina growth.

COVID-19 Impact
Alumina is made from bauxite, which is a raw material. The COVID-19 epidemic has hampered bauxite mining, which has been labeled a national emergency by governments around the world. The market has been severely impacted by disruptions in bauxite production and supply to alumina refineries.
Spikes in COVID-19 infection rates resulted in lockdowns and shutdown of mining activities. Moreover, several industries such as Alumina stopped production due to lockdown protocols. As governments across the world are relaxing restrictions, it is projected that the pre-pandemic sales levels would be surpassed.
Key Developments
Due to its improved safety and performance, advanced aluminum materials are overtaking the automotive industry. Since lightweight materials improve fuel efficiency, worldwide automakers are switching their preferences to lighter materials in lieu of iron and steel components.
For instance, in 2020 itself, International Aluminum Institute (IAI) recorded 10,943.0 thousand metric tons of alumina production amid the surging COVID-19.
Refractories, ceramics, polishing, and abrasive applications are the most common applications for speciality aluminum oxides. Aluminum hydroxide, from which alumina originates, is used to make zeolites, coat titania pigments, and as a fireplace retardant/smoke suppressant in large quantities. Over 90% of the alumina, commonly referred to as Smelter Grade Alumina (SGA), is used in the Hall–Héroult process, which is used to assemble aluminum.
Also, Aluminum oxide has a number of advantages, including the ability to be produced in a range of forms, such as powder, sputtering targets, and tablets. Aluminum oxide can also be obtained in the form of nanoparticles. Aluminum oxide nanoparticles have a high tensile strength. Additionally, the particles have electric conductivity, are ductile, and can be employed to improve the strength of a variety of metals and alloys.
Competitive Landscape
Although rising demand from the automotive, construction, and packaging industries is likely to drive up aluminum demand, the global market is expected to face several constraints due to changing raw material prices and the availability of alternative materials. Yet, the competitive landscape is experiencing constant acquisitions, mergers, and expansions.
- Aluminum Corporation of China Ltd. (Chalco) began development on the second alumina refinery production line at Huasheng, China, in November 2020.
- Gränges AB, a Swedish rolled aluminum company, and Alcoa Corp, an American aluminum pioneer, have launched a collaboration in June 2021, focused at lowering the environmental effect of the aluminum value chain.
- Kaiser Aluminum Corporation had concluded its $670 million acquisition of Alcoa Warrick LLC in April 2021, which included all of the assets of the Warrick Rolling Mill, from Alcoa Corporation (“Alcoa”).
Some prominent players of the market include:
- Alcoa Corporation
- Hongqiao Group
- Vedanta
- Cabot Corporation
- Aluminum Corporation of China (Chalco)
- Worsley Alumina
- Sasol
- Almatis
- Rusal
- Xinfa Group
