Sodium Fluoride Evaporation Materials Description
Sodium fluoride is a compound composed of sodium and fluorine, forming a colorless crystalline solid with a cubic crystal structure. When used as an evaporation material, sodium fluoride exhibits several key characteristics that make it suitable for thin film deposition:
- High Melting Point: Sodium fluoride possesses a relatively high melting point of around 993°C (1819°F). This characteristic allows it to withstand the heat generated during the deposition process without premature sublimation.
- Stable Vapor Pressure: Sodium fluoride has a stable vapor pressure at elevated temperatures, which ensures consistent and controlled evaporation rates during the deposition process. This stability contributes to the uniformity of the deposited thin films.
- Reactive Nature: Sodium fluoride is known for its reactivity, particularly with moisture. It's important to handle sodium fluoride evaporation materials in controlled environments to avoid contamination or reaction with atmospheric moisture.
- Wide Transmission Range: Sodium fluoride thin films exhibit excellent optical transparency in the ultraviolet (UV) to infrared (IR) spectral range. This property makes them suitable for optical coatings, anti-reflective coatings, and other applications requiring precise control over light transmission.
