Alumina Hollow Spheres

Product Name: Alumina Hollow Spheres, Silicon Carbide Hollow Spheres;

Specification: 0.5-1mm (Customizable);

Hollow Diameter: 0.6 ± 0.1mm;

Wall Thickness: 0.15-0.2mm;

Shape: Alumina (White), Silicon Carbide (Dark Green) Spherical Granules;

Composition: Aluminum Oxide (Al₂O₃), Silicon Carbide (SiC);

CAS Number: Aluminum Oxide Al₂O₃ (1344-28-1), Silicon Carbide SiC (409-21-2);

Chemical Property: Inert;

Dust Rate: <0.001%;

Compressive Strength: Alumina 0.5-1mm > 40 N/pellet, Silicon Carbide 0.5-1mm >60 N/pellet;

Bulk Density: 1.2 ± 0.1 g/cm³;

Applications:

Used in composite materials for high-temperature resistance and impact resistance. Silicon carbide/alumina is processed through a special technique to form an internal hollow structure, followed by high-temperature calcination, resulting in spherical granules with advantages such as light weight and high compressive strength.
