Inert Alumina Ceramic Ball are widely used in many fields,such as petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection, etc. Which function mainly as the covering and supporting materials for catalyst in reactors and packing for towers. Its principal role is to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.
In accordance with the different content of AL2O3,it can be divided into as follows:
Product name Item | Low Alumina Ball | Middle Alumina Ball | High Alumina Ball | |
Al2O3 | 17-35% | 60-75% | 80-99% | |
Al2O3 +SiO2(%) | ≥92% | ≥92% | ≥99% | |
Fe2O3(%) | <1% | <1% | <0.5% | |
CaO (%) | <1.5% | <2.1% | <2.9% | |
MgO (%) | <2.5% | <1.3% | <0.5% | |
K2O+Na2O(%) | <4.0% | <4.0% | <4.0% | |
