- Customized Alumina for Battery Applications
High-purity alumina is used in battery separators to improve the long-term safety and performance of LIBs. Ceralox products are designed to have narrow particle-size distribution both in powder as well as in composite polymer films. The ultra-low contaminant levels and finely tuned particle sizes provide improved performance for ceramic-based coatings.
