Description

Rhodium Evaporation Materials are highly specialized products used in physical vapor deposition (PVD), a method employed to produce thin films and coatings of rhodium over various substrates. Rhodium, a rare and precious metal in the platinum group, is esteemed for its exceptional properties, including high reflectivity, excellent corrosion resistance, and significant hardness. These characteristics make rhodium-coated materials highly sought after in numerous industrial, electronic, and decorative applications.

High-purity evaporation materials play a crucial role in deposition processes to ensure high-quality deposited films.

Properties of Rhodium

  • High Melting Point: Rhodium’s melting point is approximately 1,964°C (3,567°F), which requires a high energy input for vaporization.
  • Corrosion Resistance: It is highly resistant to corrosion and oxidation, making it an excellent choice for protective coatings.
  • Reflectivity: Rhodium’s excellent reflectivity is ideal for mirror and jewelry finishing.
  • Electrical Conductivity: It is a good conductor of electricity, making it valuable in electrical contacts and connectors.

Evaporation Process

Evaporating rhodium to form thin films involves heating rhodium evaporation materials until they vaporize. This vapor then condenses on the substrate, forming a thin rhodium coating. The evaporation can be carried out in various environments, including vacuum and controlled atmospheres, depending on the desired properties of the final product.

Forms of Rhodium Evaporation Materials

Rhodium evaporation materials come in several forms, tailored to different evaporation techniques and applications. These include:

  • Pellets and Granules are small, uniform pieces that are easy to handle and measure, ideal for precise deposition processes.
  • Rods and Wires are used for continuous feed evaporation processes, where material is gradually fed into the evaporation source.
  • Foils and Sheets: Thin layers of rhodium that can be evaporated using resistance heating or electron beam techniques.

Applications

Rhodium Evaporation Materials find applications across various sectors, including:

  • Electronics: It is used to manufacture reflective layers for optical devices, electrical contacts, and connectors due to its excellent conductivity and corrosion resistance.
  • Jewelry and Decorative: For coating jewelry and watch components, offering a reflective and tarnish-resistant finish.
  • Automotive: In catalytic converters and reflective coatings for lights and mirrors.
  • Optical and Glass Industry:  Producing highly reflective mirrors and coatings on glass or lenses.

Packaging and Handling

Handling and storage of rhodium materials require care to prevent contamination, ensuring the purity of the deposited film. Our Rhodium Evaporation Materials are clearly labeled externally to ensure efficient identification and quality control. To prevent any damage during storage or transportation, we take great care.
