Characteristics
These balls are produced with a high percentage of alumina in its highest degree of calcination, which confer them high mechanical properties and high resistance to the thermal stress. Due to its elevated purity and low silica content, these balls are specially designed for top temperatures applications in harsh environments, where we can find the action of acids and steam at high temperatures.
The HITO®-99 ball is especially recommended for the utilization as a catalyst support in the chemical and petrochemical industries. It is also used exclusively in the “secondary reformer” of the fertilizing plants, during the production of the urea ammonia. Moreover, these balls are also recommended as filler in Packing Towers.
These balls are also successively being used in Heat Exchange applications such as the regerative burners, and also in the filters DBF (“Deep Bed Filter”) in the metal casting industries.
- Very high hardness and mechanical resistance
- Excellent wear resistance
