High Purity Zinc Sulfide (ZnS) for Infrared Transmission with Customizable Particle Size

Zinc Sulfide (ZnS, CAS 1314-98-3) is an inorganic compound widely used for its unique optical, chemical, and physical properties. It occurs naturally as the mineral sphalerite but is commonly produced synthetically for industrial applications. Zinc Sulfide is valued for its high refractive index, excellent infrared transmission, and phosphorescent characteristics. It is available in various forms including powder, crystals, and coatings, making it suitable for diverse high-tech and manufacturing sectors.

• Optical Transmission: Excellent transmission in the infrared (IR) spectrum, ideal for lenses, windows, and optical coatings.
• Luminescence: Acts as a phosphor in electroluminescent displays, LEDs, and glow-in-the-dark materials.
• Pigmentation: Used as a white pigment in plastics, ceramics, and paints due to its high opacity and stability.
• Catalysis: Serves as a catalyst in certain chemical reactions, including hydrocarbon processing.
• Semiconductor Properties: Applied in photovoltaic devices, sensors, and thin-film electronics.
• UV Absorption: Provides UV-blocking capabilities in coatings and composites.

• Optics & Infrared Systems: Windows, lenses, and domes for thermal imaging, missile guidance, and night-vision equipment.
• Electronics: Phosphors in cathode ray tubes (CRTs), X-ray screens, and electroluminescent panels.
• Paints & Coatings: Anti-corrosive and UV-resistant coatings for automotive, aerospace, and marine industries.
• Plastics & Ceramics: Additive for improving whiteness, strength, and thermal stability.
• Security & Printing: Used in security inks, fluorescent markers, and anti-counterfeiting technologies.
• Photovoltaics: Buffer layer in thin-film solar cells (e.g., CIGS solar cells).
• Research & Development: Material for experimental physics, nanotechnology, and semiconductor studies.
