4N (99.99%) Chromium (Cr) Pieces Evaporation Materials
Introduction:
Chromium evaporation materials are solid substances primarily composed of chromium specifically engineered for use in thermal evaporation processes. These materials typically come in various forms such as pellets, rods, wires, or sheets, suitable for vaporization in vacuum environments.
During the thermal evaporation process, the solid chromium material is heated to its vaporization temperature, causing it to transition directly from a solid to a vapor state. The vaporized chromium then condenses onto a substrate surface, forming thin films or coatings with desired properties.
Chromium evaporation materials find applications in various industries due to chromium’s unique properties, such as high hardness, corrosion resistance, and aesthetic appeal. They are commonly used in decorative coatings, corrosion-resistant layers, and functional films for applications ranging from automotive trim to electronic devices and optical components.
Properties of Chromium Evaporation Materials:
1. Hardness and Brittleness
Hardness: Chromium is characterized by its high hardness, contributing to its durability and resistance to wear and abrasion.
Brittleness: Despite its hardness, chromium is also brittle, which can influence its processing and handling during evaporation processes.
2. Mirror Polish and Corrosion Resistance
Mirror Polish: Chromium is known for its ability to achieve a high mirror polish, making it ideal for decorative and aesthetic applications.
Corrosion Resistance: Chromium exhibits exceptional corrosion resistance, making it suitable for use in environments prone to rust and degradation.
3. High Melting Point and Density
Melting Point: Chromium boasts a high melting point of 1,857°C, enabling its use in high-temperature applications such as vacuum deposition.
Density: With a density of 7.2 g/cc, chromium provides sufficient material density for the formation of durable and uniform thin films during evaporation processes.
Applications:
1. Automotive Industry
Chromium finds extensive use in the automotive industry, where it is applied to form shiny coatings on wheels, bumpers, and other exterior components.
Chromium evaporation materials are utilized in automotive glass coatings, enhancing visibility and durability, and providing aesthetic appeal.
2. Photovoltaic Cell Fabrication
