Aluminum oxide substrate is widely used in the electronics industry as a base material for thin-film circuits and semiconductor devices due to its excellent electrical insulation and thermal conductivity. It serves as a crucial component in the production of LED lighting, where it acts as a heat sink to manage and dissipate heat efficiently. In the field of catalysis, it is employed as a support material for catalysts in chemical reactions, enhancing stability and performance. Additionally, it is utilized in the manufacturing of sensors, particularly in gas sensors, where its high surface area and chemical inertness improve sensitivity and accuracy. In abrasive applications, it is used as a coating material for cutting tools and grinding wheels, providing durability and resistance to wear. Its biocompatibility also makes it suitable for medical applications, such as in dental implants and prosthetics, where it ensures long-term stability and integration with biological tissues.
