Cd (Cadmium) Pellets are high-purity evaporation materials commonly used in vacuum deposition techniques, such as thermal and electron-beam evaporation. Cadmium offers distinct properties that make it suitable for thin-film applications in various industries, particularly in optics, electronics, and photovoltaics.

Key Applications:

• Photovoltaics: Cadmium is a critical material in the production of cadmium telluride (CdTe) thin-film solar cells, where it enhances energy efficiency and performance.
• Optoelectronics: Cd thin films are used in optoelectronic devices, including infrared detectors and photodetectors, due to their excellent optical and electrical properties.
• Semiconductor Coatings: Cadmium is also utilized in semiconductor applications, where it serves as a component of compound semiconductors such as CdSe and CdS, which are essential in electronic devices.
• Coatings for Anti-Corrosion: Cadmium coatings provide corrosion resistance, especially in harsh environments like aerospace and marine applications.
• Thin Film Transistors (TFTs): Cd is used in the production of TFTs for displays in consumer electronics, improving the performance and stability of the devices.

Features of Cd Pellets for Evaporation:

• High Purity: Cadmium pellets are typically available with purity levels of 99.9% or higher, ensuring the creation of defect-free, high-quality thin films.
• Low Melting Point: Cadmium has a relatively low melting point, making it easy to evaporate in deposition processes.
• Electrical Properties: Cadmium’s electrical conductivity and ability to form alloys make it valuable in semiconductor and electronic applications.
• Optical Properties: Cadmium thin films are used in optical devices due to their favorable reflective and refractive properties in certain wavelengths, especially in the IR and visible regions.
• Corrosion Resistance: Cadmium coatings offer protection from corrosion, especially in aerospace and marine equipment, by serving as a sacrificial layer to protect underlying materials.

Specifications:

• Purity: 99.9% (3N) or higher.
• Shape: Pellets, typically cylindrical or spherical for uniform evaporation.
• Melting Point: 321°C.
• Density: 8.65 g/cm³.
• Electrical Conductivity: 13.0 x 10⁶ S/m.
• Thermal Conductivity: 96.8 W/m·K.

Customization Options:

• Pellet Size: Various pellet sizes are available to fit different evaporation systems and requirements.
• Purity Levels: Ultra-high purity cadmium pellets are offered for specialized applications that demand minimal contamination.
• Packaging: Cd pellets are carefully packaged to prevent contamination and oxidation.
• Bonding Services: Bonding of Cd pellets to evaporation sources can be arranged to enhance deposition performance and stability.

Safety Considerations:

Cadmium is toxic and can pose health risks, so handling should be done with appropriate safety precautions, including protective gear and proper ventilation during evaporation.
