Barium Fluoride

Product Specification

Feature

High-purity barium fluoride (BaF₂) reaches 99.99% purity, with key impurities all controlled below 5 ppm, iron within 2.1 ppm and loss on ignition only 0.33%—significantly better than ordinary barium fluoride (typically only 98%–99% purity with free acid up to 0.2%)—delivering superior optical transmittance, crystal growth quality and thermal stability; it offers outstanding optical performance with good transmission across 0.15–12.5 μm, high transmittance over 0.2–12 μm without anti-reflection coating, 0.96–0.97 transmittance at 500 nm–9 μm, over 90% in the 2–10 μm mid- and far-infrared region, 0.42 transmittance even at 12 μm, and a low refractive index of 1.45–1.48, meeting most optical applications without AR coating and helping shorten production cycles and reduce process costs; it remains stable in dry environments up to 800°C, outperforming similar optical materials in heat resistance; its UV absorption makes it a base crystal material for infrared and ultrafast lasers, and its high radiation resistance makes it ideal for vacuum ultraviolet applications, while as a fast-response scintillator it serves nuclear physics, nuclear medicine, high-energy physics experiments and radiation detection with high-resolution, high-time-resolution capability; in glass and ceramics it raises refractive index and improves optical properties, and enhances ceramic hardness, wear resistance, surface smoothness and stain resistance; in electronics and instruments it is used in motor brushes and coating materials; in metal processing and smelting it serves as a welding flux and heat-treatment agent to remove impurities and promote melting; it also acts as a preservative for wood protection and a solid lubricant to reduce mechanical friction loss; all products are tested for physicochemical indicators before shipment, with purity and impurity content meeting industry standards and transparent technical data; packaging is flexible—plastic woven bags, moisture-proof aluminum foil bags, reinforced cardboard drums and other forms on request; safety storage guidance is provided (cool, ventilated, moisture-proof, away from fire and oxidants, never mixed with acids to prevent toxic gas), along with technical consultation on transport protection, ventilation and personal protection; and a long-term supporting supply of inorganic fluorine chemical products meets multi-level procurement needs in optics, electronics and ceramics.
