45% Inert Ceramic Ball – Catalyst Support Media
Application
45%AL2O3 Inert Alumina Ceramic Ball a variety of useful characteristics, such as being very resistant to corrosion and abrasion even in high-speed environments. With the right material combination, customers can also see a significantly reduced thermal conductivity as well as the ability to hold up in extreme temperatures.
The combination of high heat tolerances, reduced friction, and low-heat absorption allows ceramic balls to perform in demanding conditions which gives you the opportunity to spend less on systems to keep the entire process cool.
