FAQs
Q1: What is Strontium Fluoride Powder?
Strontium Fluoride is an inorganic compound that looks like a white crystalline powder. Because of its special physical and chemical properties, it plays a great role in many fields such as optics, metallurgy, dental materials, and radiation detection.
Q2: What are the major applications of Strontium Fluoride Powder?
The optical components used in Strontium Fluoride include lenses, prisms, and windows for the transmission of UV and IR light. Other uses are in applications requiring a flux in metal smelting, dental materials, scintillation detectors for radiation detection, and electronic components as a dielectric material.
Q3: Why is it that Strontium Fluoride is used in optical applications?
It has a low refractive index and thus transmits UV/IR light well, which is why it is used in optics as an optic, lens, and other component coating in laser and spectroscopic instruments.
