Zinc selenide powder is a high-purity II-VI compound semiconductor material with the chemical formula ZnSe. This product is a fine crystalline powder ranging from yellow to pale yellow in color, featuring a sphalerite cubic crystal structure and a direct bandgap of approximately 2.7 eV. It exhibits outstanding infrared optical properties, a high laser damage threshold, and excellent chemical stability. As a key foundational material, it is essential for the powder metallurgy fabrication of advanced infrared optical components, laser windows, and functional coatings.
We offer high-quality zinc selenide powder in multiple purities, particle sizes, and surface-modified options. Contact us for samples.

Infrared Optical Ceramics: Serves as the core material for producing high-performance infrared windows, lenses, and radomes via hot-press sintering.
Functional Coatings & Films: Used to create thermal spray coatings, infrared anti-reflective films, and wear-resistant protective layers for harsh optical environments.
Lasers & Nonlinear Optics: Acts as a precursor material for fabricating nonlinear optical crystals such as mid-infrared lasers and optical parametric oscillators.
Composites and Additives: Functioning as functional fillers in polymer or ceramic composites to impart specific infrared or electrical properties.
Q1: What are the primary advantages of ZnSe powder?
A1: Its core strengths lie in exceptional infrared transmittance, high laser damage threshold, and chemical stability, making it a preferred material for high-end infrared optics and laser applications.
Q2: How should powder particle size be selected?
A2: Selection depends on the final process. Submicron-grade ultrafine powder is required for high-density transparent ceramics, while processes like thermal spraying demand specific particle size distributions to ensure coating quality.
Q3: How should the product be stored?
A3: Must be stored in sealed, moisture-proof containers in a dry, light-protected environment to prevent agglomeration from moisture absorption or surface oxidation, which could impair sintering and optical properties.
Q4: Is it safe to use?
A4: Selenides exhibit moderate toxicity. Avoid inhaling dust during handling. Operate in well-ventilated areas while wearing protective equipment and adhere to chemical safety protocols.
