The product features a high purity level of 99% alpha-alumina (Al₂O₃) with extremely low radioactive isotope (U, Th) content, preventing contamination in sensitive applications.
With a density of 3.8–3.93 g/cm³, it is about two-thirds the weight of zirconia. Reducing the overall filling weight lowers operational load and decreases power consumption during grinding.
Standard sizes range from 0.1 mm to 10 mm. Custom sizing options are also available to meet specific industrial dispersion requirements.
Yes, it demonstrates exceptional chemical stability, offering strong resistance to acids, alkalis, and high temperatures, making it suitable for refractories and harsh chemical processing.
The material exhibits superior wear resistance, with a wet wear rate of ≤0.60% and a dry wear rate of ≤0.45%.
