More info
Alumina (Al2O3) Ceramic Balls, made from high-purity alumina, are high-performance fillers with excellent wear, heat, and oxidation resistance. They are unsuitable for use with hydrochloric acid, hydrofluoric acid, and strong alkaline solutions. In reactors and tower packing, these balls support and protect low-strength active catalysts and enhance gas or liquid distribution.
