Bubble alumina Spheres are advanced lightweight materials made from high-quality bauxite.
They possess low density, high strength, and excellent resistance to high temperatures and chemical corrosion.
Their hollow structure gives them unique advantages, such as good thermal insulation and a larger specific surface area, making them ideal for use in refractory materials and adsorbents.
Bubble alumina are produced using precise sintering techniques, resulting in a uniform and stable structure.
Depending on the specific application requirements, these spheres can be produced in various sizes and compositions to meet the needs of different industries.
