READ MORE1.Key Properties of Strontium Fluoride (SrF₂)
Strontium Fluoride (SrF₂) is a white crystalline powder with a cubic crystal structure, offering superior optical and chemical characteristics that make it indispensable in high-tech industries.
Physical & Chemical Stability
Thermal Resistance: Strontium Fluoride remains stable in air but undergoes oxidation to strontium oxide (SrO) at temperatures exceeding 1000°C, making it suitable for high-temperature processes.
Moisture Resistance: Unlike other fluorides, SrF₂ exhibits excellent stability under normal atmospheric conditions, ensuring long shelf life and consistent performance.
Solubility & Reactivity
Water & Acid Solubility: SrF₂ is soluble in water and hydrochloric acid (HCl), facilitating its use in liquid-phase chemical processes.
Hydrofluoric Acid (HF) Resistance: Unlike many fluorides, it is insoluble in hydrofluoric acid, making it ideal for applications requiring HF resistance, such as optical coatings and semiconductor manufacturing.
Optical Properties
High UV & IR Transparency: Strontium Fluoride has a wide transmission range (from UV to mid-IR), making it a preferred material for laser windows, lenses, and infrared optics.
Low Refractive Index: Its optical clarity and minimal light scattering make it valuable in precision optical devices and laser systems.
At Nantong Jinxing Fluorides Chemical Co., Ltd., we ensure that our SrF₂ meets 99.9% purity levels, with strict adherence to ISO9000 quality management systems. Our in-house R&D team continuously optimizes production techniques to enhance performance for specialized applications.
2.Wide-Ranging Applications of Strontium Fluoride (SrF₂)
Strontium Fluoride is a versatile material with applications spanning dental care, optical technology, pharmaceuticals, and industrial manufacturing.
Dental Care & Toothpaste Additives
Enamel Strengthening: Due to its fluoride-releasing properties, SrF₂ is used in anti-cavity toothpaste formulations, helping to remineralize tooth enamel and prevent decay.
Safe Fluoride Source: Unlike some fluoride compounds that may cause irritation, Strontium Fluoride offers a gentle yet effective solution for oral care products.
Research & Innovation: Nantong Jinxing Fluorides collaborates with dental research institutions to develop advanced fluoride-based formulations for preventive dentistry.
Optical & Laser Technology
Laser Crystals & Windows: SrF₂’s excellent transmittance in UV and IR spectra makes it ideal for CO₂ laser systems, excimer lasers, and optical coatings.
Infrared Optics: Used in thermal imaging devices, military-grade night vision systems, and aerospace sensors due to its durability and clarity.
Fluorescent Screens: Enhances brightness and color accuracy in CRT displays, X-ray intensifying screens, and LED phosphors.
Pharmaceutical & Chemical Manufacturing
Drug Formulations: SrF₂ serves as a precursor in strontium-based pharmaceuticals, particularly in treatments for osteoporosis and bone density enhancement.
Catalyst & Reagent: Used in organic synthesis and specialty chemical production due to its stable fluoride release properties.
Industrial & Specialty Applications
Welding & Metallurgy: Acts as a flux agent in aluminum and magnesium welding, improving joint strength.
Glass & Ceramics: Enhances the refractive index and thermal stability of specialty optical glass.
