99% Alumina Ceramic Ball
99% Alumina Ceramic Ball
Product Description.
The Chemxin 99 High Alumina Support Media is in chemical composition 99+% alpha alumina and a maximum 0.2wt% SiO2. Because of its high alumina content and low silica (SiO2 ), it's a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
High-alumina ceramic balls are widely used as catalyst carriers in the petroleum, chemical, power and other industries due to their high hardness, high wear resistance and good thermal stability. During the reaction process of the catalyst, high-alumina ceramic balls can effectively disperse the catalyst and improve the activity of the catalyst, thereby improving the reaction efficiency. In addition, its excellent thermal stability enables high-alumina ceramic balls to maintain stable performance under high temperature conditions, further extending the service life of the catalyst.
