Bismuth (Bi) pellets are high-purity materials designed for use in thin film deposition processes, particularly physical vapor deposition (PVD) techniques such as thermal evaporation or electron-beam evaporation. Bismuth is a heavy metal known for its low toxicity, high density, and unique electronic properties, making it valuable in a range of applications, from optical coatings to thermoelectric materials.

Key Applications:

• Thermoelectric Devices: Bismuth is widely used in thermoelectric materials, where it forms compounds like bismuth telluride (Bi2Te3) for efficient energy conversion in Peltier coolers and power generation.
• Optical Coatings: Bismuth is applied as a thin film in optical coatings due to its refractive properties, improving performance in infrared (IR) and visible light regions.
• Magnetic and Superconducting Materials: Bismuth-based films are used in advanced magnetic materials and superconductors for research and technology development.
• Semiconductor Industry: Bismuth thin films play a role in the fabrication of certain semiconductors and electronic components due to their unique electrical properties.
• Energy Storage: In advanced battery technologies, bismuth is explored for use in electrodes to enhance battery performance.

Features:

• Low Toxicity: Bismuth is one of the few heavy metals considered relatively non-toxic, making it a safer alternative for certain applications.
• Unique Electrical Properties: Bismuth exhibits interesting electronic properties, such as a high Hall coefficient and low thermal conductivity, beneficial for thermoelectric applications.
• High Density: Bismuth’s high atomic mass and density make it suitable for applications requiring heavy elements.
• Low Melting Point: With a melting point of 271.4°C, bismuth is relatively easy to evaporate, allowing for low-temperature thin-film deposition.
• Optical Characteristics: Bismuth coatings can manipulate light in specific wavelengths, contributing to its use in optical and IR coatings.
