Strontium Fluoride

Product Specification

Feature

Wide spectral transmission suitable for professional optical components. Strontium fluoride supplied by Changzhou Jiayuan Chemical is a white solid or powder with the chemical formula SrF₂, CAS number 7783-48-4, and molecular weight of about 125.62; relevant basic data are included in the NIST chemistry database. Strontium fluoride has a wide transmission range from the ultraviolet to the long-wave infrared region, with a transmission range of approximately 0.15-11 μm, and features low dispersion and low reflection loss. It can be used in the manufacture of optical windows, lenses, prisms, and infrared optical system components, making it suitable for professional applications requiring wide-band transmission performance. Actual optical performance depends on crystal quality, surface processing, and component design. Low hygroscopicity and good surface properties support optical processing requirements. Strontium fluoride belongs to the cubic fluorite-structure crystal system. Optical material data show that the material has good surface hardness and is not easily hygroscopic, which is beneficial for the processing and use of specific optical components. Its melting point is about 1450°C and density about 4.24 g/cm³, providing basic parameters for material selection and structural design. The above data are reference values and do not mean that all grades or batches have exactly the same indicators; for precision optical applications, purity, impurity content, crystal quality, and inspection documents provided by the supplier should still be verified. Specifications confirmed by application with emphasis on batch quality and safety management. Strontium fluoride is a material for professional use, and different optical systems have different requirements for purity, transmission performance, impurities, and size specifications. Jiayuan Chemical can assist customers in clarifying technical indicators, testing methods, packaging, and quality document requirements according to the final application, facilitating evaluation of the match between raw materials and processes and supporting batch quality traceability. During operation and storage, dust generation should be avoided, contact with eyes and skin should be prevented, and strong acids and other incompatible substances should be kept away; specific protective measures are subject to the safety data sheet SDS of the corresponding product. We are committed to providing standardized fluoride chemical product supply and related services for optical material, electronic material, and research customers.
