Inert Alumina Ball-90
Al2O3 content: 90%~92%
Packing density: 1900~2000kg/m3
National standard: HG/T 3683.1-2014
Loading capacity: 25 tons max by 20”GP & 40”GP.
Application: As catalyst carriers, such as in catalytic cracking, reforming and other reaction processes.
Description：
Inert alumina ball-90 is also called high inert alumina balls, which refer to the alumina content of over 90%. Its main raw material is alpha alumina powder, rolled or pressed into shape. In general, it can tolerate the temperature up to 1550 degrees or even higher.

| Description： Inert Alumina Ball-90 have extremely high hardness and wear resistance, and are not easily worn out during long-term use. The ball shape is round and the surface is smooth. At the same time, it has extremely high mechanical strength, can withstand large pressures and impacts, is not easy to break, and has stable performance. The most important thing is that alumina balls with higher aluminum content and stronger high-temperature resistance. At the same time, ceramic alumina balls are inert, so they have good corrosion resistance to chemicals such as acid and alkali, and are not easily corroded by chemicals. |
