Applications:
Ceramics: Used as a sintering aid and microstructure modifier in technical ceramics, where gamma-Al₂O₃ enhances densification, reduces grain growth, and improves mechanical integrity at lower firing temperatures.
Catalysis: Serves as a high-surface-area support for metal catalysts in heterogeneous reactions, particularly in petrochemical and environmental catalysis, due to its thermal stability and porous morphology.
Coatings: Incorporated into protective and functional coatings to improve hardness, abrasion resistance, and thermal insulation, especially in transparent or thin-film systems where nanoparticle dispersion uniformity is critical.
Polishing & Abrasives: Applied in precision polishing of optical components, semiconductors, and metals, where controlled particle size and hardness enable uniform material removal and surface smoothness.
Electronics: Used in dielectric layers, insulating films, and thermal interface materials, where gamma-Al₂O₃ contributes to high breakdown strength, low dielectric loss, and thermal conductivity enhancement.
Environmental: Explored in water purification and adsorption systems, where its high surface area and surface hydroxyl groups support the removal of heavy metals, fluorides, and organic pollutants.
