Inert Alumina Ceramic Ball
A detailed description of
Chemical characteristics of Inert Alumina ceramic ball：
It functions 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 3 categories:
