Applications:
Aluminum Oxide (Al₂O₃) nanodispersion finds extensive use across various industries:
Ceramics: Acts as a sintering aid and grain growth inhibitor in advanced ceramic formulations, enhancing densification and mechanical strength at lower processing temperatures.
Catalysis: Serves as a high-surface-area support for heterogeneous catalysts in petrochemical and fine chemical synthesis, improving dispersion and thermal stability of active sites.
Coatings: Incorporated into functional coatings for scratch resistance, thermal insulation, and UV protection, particularly in transparent or thin-film systems.
Polishing & Abrasives: Used in precision polishing of semiconductors, optics, and metals due to controlled particle size and hardness, enabling uniform surface finishing.
Electronics: Applied in dielectric layers and insulating films where gamma-phase Al₂O₃ ensures high breakdown strength and low leakage currents.
Biomedical: Explored for drug delivery carriers and implant coatings, leveraging its biocompatibility and ability to form stable dispersions for controlled release.
Environmental: Utilized in water purification and adsorption systems, with its high surface area aiding in the removal of heavy metals and organic contaminants.
