Description
Yttrium Fluoride (YF₃) Nanopowder – Purity: 99.9%, APS: <50 nm
Product Overview
Yttrium Fluoride (YF₃) Nanopowder is a high-purity, fine-grain, white powder widely used in optical coatings, phosphors, and specialty ceramics. Thanks to its excellent thermal and chemical stability, YF₃ nanoparticles are particularly valuable in high-temperature environments and as host materials in up-conversion luminescent systems. Their nanoscale size enhances surface area and dispersion in composites, enabling precise control in material design.
