Alumina spheres and activated alumina spheres are types of spherical particles made primarily from aluminum oxide (Al2O3), commonly known as alumina. Keeping in tune with our commitment to innovation and up gradation we expanded our portfolio of filtration and purification products to include activated alumina balls.Keeping in tune with our commitment to innovation and up gradation we expanded our portfolio of filtration and purification products to include activated alumina balls. With their high water adsorption capacity and large surface area, activated alumina balls are the most efficient solution for oil filtration, compressed air & gas drying processes and for fluoride removal from aqueous solution are long tasting and thus cost-effective.With their high water adsorption capacity and large surface area, activated alumina balls are the most efficient solution for oil filtration, compressed air & gas drying processes and for fluoride removal from aqueous solution are long tasting and thus cost-effective.Alumina spheres are spherical particles primarily composed of aluminum oxide (Al2O3). They are often used as catalyst supports, adsorbents, and packing materials in various chemical and industrial processes.They are often used as catalyst supports, adsorbents, and packing materials in various chemical and industrial processes.
