产品描述

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:
