Magnesium Fluoride

Product Specification

Feature

Product selling points: Electronic-grade magnesium fluoride with purity ≥99.95% and extremely low metal impurities (Fe only 2.4 ppm; Co, Cr, Ti, Cu, Mn, Ni, V all below 1 ppm) for high-performance optical coatings; stable refractive index of about 1.38 (@550nm) with batch-to-batch fluctuation within ±0.005, reducing process adjustment risks for multilayer coating customers; transmission range from 120nm to 7μm covering UV to IR, suitable for UV lenses, windows, infrared optical instruments, and missile dome coatings; hot-pressed polycrystalline magnesium fluoride achieves IR transmittance above 90% in the 3–5μm mid-wave IR band at 2mm thickness, with high mechanical strength and thermal shock resistance; industrial-grade product purity ≥98% with low loss on ignition, suitable for ceramic/glass fluxing, magnesium smelting flux, and aluminum electrolysis additives; standardized 25kg kraft paper bags with PE liner, palletized and stretch-wrapped, with customized packaging available; technical support for selecting specifications based on coating process conditions, sample testing support, and complete SDS/COA with each batch for traceability and compliance; helps reduce reliance on imports and stabilize supply.
