📌 Product Overview
Chemical formula: LiF | Molecular weight: 25.94 | CAS number: 7789-24-4
Appearance: white crystalline powder (cubic system, NaCl type structure)
Key features:
High melting point: 842℃ (resistant to high temperature electrolysis environment)
Transmittance: 0.12~8.5μm UV-infrared band transmittance (core indicator of optical devices)
Solubility: 0.29g/100mL water (20℃), soluble in acid
Hazard level: UN 3288 (Class 6.1 toxic substances), professional packaging and transportation required
⚡ Core applications and technological advantages
1. 🔋 Revolutionary materials for new energy batteries
Solid electrolytes: inhibit lithium dendrites and improve ionic conductivity (suitable for lithium metal negative electrode batteries)
Precursor synthesis: preparation of lithium hexafluorophosphate (LiPF₆), purity ≥ 99.99%
Nanotechnology: 20nm particle size lithium fluoride improves SEI film stability and extends cycle life by 300%
2. 🔭 Core components of high-end optical devices
Ultraviolet window materials: refractive index 1.3915, used for deep ultraviolet lasers and space telescope lenses
X-ray monochromator: crystal purity > 99.99%, reducing scattering losses
3. ☢️ Key auxiliary materials for nuclear energy technology
Neutron shielding: enriched ⁶Li isotopes (capture thermal neutron cross section up to 940 barn)
Molten salt reactor solvents: resistant to radiation decomposition, suitable for the fourth generation nuclear reactor design
4. 🏭 Industrial efficiency enhancement application
Aluminum electrolysis additive: reduce molten salt viscosity, increase current efficiency by 15%
Special glass fluxing: reduce glaze sintering temperature to 720℃ (energy saving solution)
