Product Description

1. Product Description
Refractory ceramic balls are made from industrial alumina and other raw refractory materials, and processed by mixing, shaping and firing. it has properties of

1) Excellent resistance to high temperature up to 1900℃.

2) High chemical stability, without reaction with the feeding materials;

3) High strength and long service life, electrical insulation;
Refractory ceramic balls can be used as support and covering packings for catalyst in shift converter,reformer, hydro converter, desulfurizer, and methanator, and can also be used as packings in hot blast heater and heat transformer in iron and steel industries.
