aluminum oxide can be used in the manufacture of refractory materials, electronic base materials, and the electrolytic production of metal aluminum, among other fields. This dataset includes the main raw materials, auxiliary materials, energy, and atmospheric emissions of the production process. Production equipment, plant construction, and other infrastructure are not within the scope of the dataset boundary. The data inventory is sourced from literature and has been optimized and modeled according to the best available information for 2022. The process flow for aluminum oxide production using the sintering method includes crushing, batching, sintering kiln, clinker dissolution, red mud separation, sodium aluminum oxidete decomposition, and calcination of aluminum hydroxide.
