Magnesium fluoride plays an irreplaceable role in high-end lenses, infrared windows, and precision optical coatings. Leveraging years of fine chemical manufacturing experience, Changzhou Jiayuan Chemical has become a reliable force among professional suppliers of magnesium fluoride.

Material Properties

Magnesium fluoride features an extremely low refractive index (1.38 @ 550 nm) and a transmission range covering 120 nm to 7 μm, exhibiting excellent performance from deep UV to mid-infrared. Coupled with good chemical and thermal stability, it serves as an ideal substrate material for anti‑reflective coatings, infrared windows, and other optical components.

Electronic‑Grade Magnesium Fluoride: Advantages and High‑End Applications

In the field of high‑end manufacturing, the electronic‑grade magnesium fluoride supplied by Changzhou Jiayuan Chemical stands out. The product purity can reach over 99.95%, and key impurities such as iron, cobalt, and nickel are strictly controlled at the ppm level. This ensures that no absorptive defects occur during the coating process, thereby safeguarding the transmittance and imaging quality of optical devices.

Downstream Applications

Optical Coating and Precision Lenses: As an anti‑reflection layer, magnesium fluoride significantly reduces surface reflection of lenses and increases luminous flux. It is widely used in DSLR cameras, projectors, and LiDAR optical systems.

Infrared Optics and Defense Technology: On mid‑infrared windows, missile domes, and space detectors, magnesium fluoride combines transparency with resistance to environmental erosion, making it a key material in military and aerospace applications.

Semiconductors and Flat‑Panel Displays: High‑purity magnesium fluoride is used in etching masks for chip manufacturing and as a protective layer in OLED encapsulation. Its electrical insulation and low dielectric loss properties enhance device stability.

In addition, electronic‑grade magnesium fluoride also plays important roles in both traditional and emerging fields such as microwave dielectric ceramics, LTCC substrates, and aluminum electrolysis fluxing agents.
