Import 99.99% Mgf2 Magnesium Fluoride Crystal — Buy in wholesale FOB from Supplier in China

This listing offers magnesium fluoride in crystal granule form, with a stated purity of 99.99% and CAS number 7783-40-6. The material is supplied as colourless transparent granules in two standard size fractions: 1-3 mm and 3-5 mm. Density is 3.18 g/cm³ and melting point is 1266 degrees Celsius. The refractive index at 550 nm is 1.38, with a broad transparency range from 0.11 to 10 micrometres. The supplier indicates evaporation sources of boron with tungsten, tantalum, or molybdenum. Each unit is packaged as 1 kg per bag, with storage instructions to avoid sunlight, acid exposure, and moisture.

MgF2 is an intrinsic crystal grown from the melt, prized in optical coating applications for its low refractive index and wide transmission window from the vacuum ultraviolet through to the mid-infrared. The 99.99% purity grade is typical for thin-film deposition where trace metal impurities would degrade laser damage threshold or introduce absorption losses. Crystal granule morphology is preferred over powder for electron-beam evaporation, as the fused structure minimises outgassing and spatter during heating. Standard industry grades for optical coating range from 99.9% to 99.99%; the higher grade here suits precision optics and laser systems where scatter must be minimised. The material is hygroscopic to a limited degree, so sealed packaging and dry storage are standard practice across the trade.

Buyers are primarily optical coating houses, precision optics manufacturers, and research institutions running physical vapour deposition systems. Applications named by the supplier include multi-layer coatings, anti-reflection (AR) coatings, decorative coatings, spectacle lens coatings, and ultraviolet coatings. The 1 kg packaging suits smaller deposition runs or R&D batches; production houses typically require larger consignments. The supplier's address places it in Taizhou, Jiangsu Province, with the harbour trust tier. Response rate is currently showing as 0.00%, so direct enquiry is essential to confirm current stock, exact granule size availability, and whether larger packaging options exist.

Taizhou Ats Optical Material Co., Ltd. is located at No.28, Zhennan Alley, Baimi Town, Jiangyan District, Jiangsu Province, Taizhou, 225500, China. The company holds a harbour trust tier on the platform, and its response rate is currently recorded as 0.00% with an average response time of 0 hours, suggesting either a new listing or inactive enquiry management. No workforce size, revenue figures, or year of establishment are stated in the profile. The listing focuses exclusively on magnesium fluoride crystal products, specifically the granule form for thin-film deposition.

The supplier positions itself as following critical manufacture standards and offering quality assurance, though no specific certifications (ISO, RoHS, REACH) are named in the available美少女available data. The product range is narrow: one category of magnesium fluoride crystal, with the photographed item being crystal granule. Buyers should note that the profile does not disclose export experience, client references, or in-house testing capabilities. Direct contact is necessary to verify quality control protocols, batch consistency documentation, and whether the company offers certificates of analysis with each lot.
