Zinc Telluride Powder

Zinc Telluride Powder Description

Zinc Telluride (ZnTe) powder from TFM is a high-purity, semiconductor-grade material widely used in infrared optics, thin film deposition, photodetectors, and solar cells. As a II-VI compound semiconductor, ZnTe exhibits a direct band gap of ~2.26 eV at room temperature, making it ideal for optoelectronic devices and infrared (IR) applications.

Zinc Telluride powder is commonly utilized in:

  • PVD and CVD deposition for ZnTe thin films

  • Buffer and window layers in CdTe-based solar cells

  • IR optical coatings and acousto-optic devices

  • Thermoelectric and photoconductive materials

  • Quantum dot and nanoelectronics research

TFM supplies ZnTe powder in various purities and particle sizes to meet research and industrial standards.

FAQ

  • Metal powders are fine particles of metals produced through various processes such as atomization, reduction, or electrolysis. They are used in applications like additive manufacturing, powder metallurgy, and coatings.

  • Alloy powders consist of two or more metallic elements combined to enhance properties like strength, corrosion resistance, and ductility, whereas pure metal powders contain only a single element.

  • The shape affects flowability, packing density, and spreadability. Spherical particles are preferred in additive manufacturing due to their superior flow characteristics.

  • Spherical powders are typically produced using gas atomization, where molten metal is atomized into fine droplets that solidify into spherical shapes.

  • Spherical powders offer better flowability and packing density, leading to improved layer uniformity and mechanical properties in 3D-printed components.

  • Factors include particle size distribution, shape, chemical composition, purity, and production method.

  • Yes, metal powders can pose hazards such as toxicity, reactivity, combustibility, and instability. Proper handling, storage, and safety protocols are essential.

  • In powder metallurgy, metal powders are compacted and sintered to produce components with complex shapes and tailored properties, often with minimal waste.

  • Yes, unused or excess metal powders from manufacturing processes can often be collected, sieved, and reused, provided they meet quality standards.

  • The combination of different metals in alloy powders can enhance properties such as strength, hardness, corrosion resistance, and thermal stability, depending on the application requirements.

  • Spherical alloy powders are used in aerospace, automotive, medical implants, and tooling industries for manufacturing high-performance components via additive manufacturing and powder metallurgy.

Production methods like gas atomization, water atomization, and mechanical milling influence particle size, shape, and purity, which in turn affect the performance of the powders in various applications.
