· JVASP-26742· LuSF

LuSF is a lutetium-based fluoride ceramic compound, representing a specialized material within the rare-earth fluoride family. Its high density and elastic properties make it relevant for applications requiring rigid structural or optical performance in demanding thermal or chemical environments. This material family is primarily explored in research contexts for advanced optics, scintillation detection, and specialized high-temperature applications where rare-earth fluorides offer superior chemical stability and radiation resistance compared to conventional oxides or silicates.
