| General description: | Nanosized aluminum oxide, also called nano alumina or Al2O3 nanoparticles, is a form of aluminum oxide with a small particle size and high specific surface area. Our aluminum oxide nanoparticles have a particle size less than 50 nm. The nanoparticles are suspended in isopropyl alcohol (IPA) to facilitate its dispersion and use. Nano alumina exhibits unique bio-physicochemical properties, including high surface area, high hardness, thermal stability, and biocompatibility. In the field of catalysis, it servesas efficient catalyst supports, enhancing reaction rates and selectivity. They also exhibit remarkable dielectric properties, making them valuable for electronic and optoelectronic devices. Additionally, Al2O3 NPs have demonstrated promising results in biomedical applications, including drug delivery systems, biomedical imaging, biosensing, and tissue engineering. They are also key components in advanced coatings, energy storage systems, environmental remediation, optoelectronics, photonics, and personal care products. |
