The hydrate is then calcined to produce anhydrous alumina, a white, granular material.

Alumina's primary use is in the production of aluminum metal via the Hall–Héroult process. In this electrolytic process, alumina is dissolved in molten cryolite, and an electric current is passed through the solution, resulting in the deposition of aluminum at the cathode. Aluminum is prized for its lightweight, corrosion resistance, and high strength-to-weight ratio, making it essential in aerospace, automotive, construction, and packaging industries. Besides aluminum production, alumina is also used in various other applications:

• Ceramics: Alumina is used in manufacturing high-strength ceramics for applications such as cutting tools, insulators, and biomedical implants.
• Refractories: Its high melting point makes alumina suitable for use in refractory materials that line furnaces and kilns.
• Abrasives: Alumina is employed as an abrasive in grinding wheels, sandpaper, and polishing compounds.
• Catalysts: Alumina serves as a catalyst or catalyst support in various chemical processes.
• Adsorbents: Due to its high surface area, alumina is used as an adsorbent in applications such as water purification and gas drying.

The demand for alumina is intrinsically linked to the demand for aluminum. As global industrialization and urbanization continue, the need for aluminum rises, driving the demand for alumina. Therefore, companies like Hangzhou Jinjiang Group play a vital role in meeting this demand.
