Aluminum oxide hollow spheres are a new type of high-tech material, mainly composed of aluminum oxide. Aluminum oxide hollow spheres are hollow spherical particles with characteristics such as light weight, high strength, high temperature resistance, and corrosion resistance, which are widely used in various fields. In industrial production, alumina hollow spheres can be used as filling materials, catalysts, adsorbents, thermal insulation materials, etc.

Performance characteristics of alumina hollow spheres

1. Low density: The density of hollow alumina spheres is generally between 0.3-0.9g/cm3, which is about one-third to one-fifth of that of solid alumina materials. This low-density performance gives alumina hollow spheres good buoyancy and lightweight characteristics, making them suitable for fields such as aerospace and automotive industry.
2. The compressive strength of high-strength alumina hollow spheres is generally between 2-12MPa, which is 2-4 times that of conventional alumina materials. This high-strength performance ensures that the alumina hollow spheres are not easily deformed and broken under suspension or load pressure.
3. High temperature stability: Aluminum oxide hollow spheres have excellent high temperature stability and can withstand high temperature environments above 1500 ℃ without annealing deformation or carbonization damage.
4. Non magnetic: Aluminum oxide hollow spheres do not have magnetism and will not interfere with electromagnetic fields.
5. Biocompatibility: Aluminum oxide hollow spheres are non-toxic and harmless to living organisms, with a smooth surface that does not cause irritation or allergic reactions to the human body. They can be used in medical and drug control applications
