5. Thermal Stability: Fumed Aluminum Oxide demonstrates excellent thermal stability and resistance to high temperatures, making it suitable for applications in extreme conditions.
6. Low Bulk Density: Fumed Aluminum Oxide exhibits a low bulk density, which allows for better flowability and improved handling in various processes, such as powder blending, filling, and transportation.
7. Positive Surface Charge: Fumed Aluminum Oxide typically carries a positive surface charge, which can have several beneficial effects, including improved dispersion stability in liquid systems, enhanced interaction with negatively charged surfaces, and increased compatibility with certain polymers and matrices.
1. Ceramic coatings for separators in Li-ion batteries
Fumed Aluminum Oxide is used to create ceramic coatings on separators in lithium-ion batteries. These coatings enhance thermal stability and safety while improving conductivity and reversible capacitance when applied to the anode of the battery.
2. Powder coatings and printing ink
Fumed Aluminum Oxide is employed to improve the chargeability and flowability of powder coatings and printing ink, enhancing the performance and application properties of these materials.
3. Thermal boards
Fumed Aluminum Oxide finds application in various types of thermal boards, contributing to their thermal properties and overall performance.
4. Charge adsorption in meltblown electret masterbatch
Fumed Aluminum Oxide is used to enhance the charge adsorption capability of meltblown electret masterbatch, which is important in applications like filtration media for air and liquid purification.
5. Fluorescent coating powders in the lighting industry
Fumed Aluminum Oxide is incorporated into fluorescent coating powders used in the lighting industry. It helps to achieve uniform light output, reduce light attenuation, and mitigate UV harms.
6. Gloss and ink absorption improvement in papers
Fumed Aluminum Oxide, when used as a super fine powder, can enhance the gloss and ink absorption properties of papers, resulting in improved print quality and appearance.
