Strontium Fluoride Powder (SrF2, Purity: 99.6%, APS: 40-50µm)

Strontium Fluoride Powder

Strontium fluoride powder is an ideal material for optical applications and is commonly used as a coating material for high-performance optical windows, prisms and lenses to reduce reflection and increase transmission. In addition, it can be used as an inorganic filler in dental composites, and therefore can improve the mechanical and chemical properties of dental materials by acting at the same time as a fluoride-releasing material, which is of great importance in the prevention of caries. The desired effects are often enhanced by the addition of nanoscopic metal fluorides. In this study, we report for the first time the sol-gel synthesis and the general characterization of the fundamental properties of nanoscopic SrF₂ powder from strontium acetate hemihydrate precursor. The existence of SrF₂  powder dust in the highly transparent sun and in the bulk material has been demonstrated by various analytical methods such as dynamic light scattering (DLS) and X-ray powder diffraction (XRD). The use of spectroscopic and crystallographic methods (solid state NMR, XRD and wide-angle X-ray scattering WAXS) allowed us to obtain complete chemical and structural information during the fluorolysis process of strontium acetate hemihydrate while reacting with HF. Step. To better understand the gelation and aging process, WAXS measurements and NMR experiments were performed on the Strontium fluoride powder over a period of several weeks and months.
