Activated Alumina
Activated alumina is a highly porous and absorptive material made from aluminum oxide (Al₂O₃). It is widely used in various industrial applications due to its ability to absorb water, gases, and other substances. The material is created by heating aluminum hydroxide to produce a substance with a vast surface area and a network of microscopic pores.
One of the key advantages of ceramic balls is their ability to withstand extreme temperatures and corrosive environments, where traditional steel or polymer balls would fail. Their low density and high hardness also contribute to reduced wear and longer service life, making them ideal for use in high-speed bearings, where they minimize friction and enhance efficiency. Additionally, ceramic balls are non-magnetic and electrically insulating, which is critical in electronic and precision instrumentation applications.
Ceramic balls are also utilized as catalyst carriers or media in chemical processing, where their chemical inertness ensures they do not react with the substances being processed. In filtration systems, they act as support media, providing a stable surface for catalysts while allowing fluid flow.
Overall, the superior properties of ceramic balls, including durability, corrosion resistance, and low thermal expansion, make them essential components in demanding environments where reliability and performance are paramount.
