Mathym develops and manufactures innovative fluoride and oxide nanomaterial dispersions customized for high-end applications such as optics and biomaterials. Our nanoparticles are provided in a wide range of application-specific dispersion media.

zilight® (ZrO2), Mathym novel nano-zirconia, allows tunability of the refractive index while maintaining high transparency for display and optical applications such as LED, XR or ophthalmic coating. filyxio® (YbF3), our best-in-class radiopacifier for dental composites, allows the deepest curing and the most aesthetical restorations. Our highly crystallized nano-ceria (CeO2) features an exclusive narrow particle size distribution enabling exquisite removal rate and defect control in Chemical Mechanical Polishing.
