Gallium evaporation material requires a Mo/W/Ta boat or graphite/alumina crucible for thermal or resistive evaporation. The 30°C melting point and 1-5 mm shot size affect deposition source loading and process parameters.
- Evaporation Source Compatibility: Use a Mo/W/Ta boat or graphite/alumina crucible for evaporation of this material.
- Evaporation Method: Thermal or resistive evaporation is preferred, and low-power e-beam evaporation is optional.
- Melting Point: The material melts at 30°C, which may require temperature control during source loading.
- Particle Size: Shots of 1-5 mm size are suitable for standard evaporation sources.
Given gallium's low melting point of 30°C, how should the material be handled and stored to prevent premature melting or degradation before deposition?
Gallium melts at 30°C (86°F), which means it can liquefy under typical ambient conditions if stored in a warm environment. The product is supplied as solid shots, but upon melting it becomes a liquid metal that may wet surfaces or leak. Storage below 30°C is recommended to maintain the solid form, and handling should avoid extended exposure to heat sources.
What crucible and source materials are compatible with gallium evaporation, and are there reactivity concerns that limit the choice of boat or liner?
The recommended evaporation source materials are molybdenum (Mo), tungsten (W), or tantalum (Ta) boats, or graphite/alumina crucibles. Thermal/resistive evaporation is preferred; low-power e-beam is optional. Gallium can be corrosive to certain metals and may alloy with aluminum or other substrates, so using the specified refractory metals or ceramic crucibles is critical to avoid contamination or damage to the evaporation source.
Does gallium pose any special handling or safety risks during measurement, loading, or storage, such as wetting of surfaces or metal embrittlement?
Gallium is considered low-toxicity but can cause metal embrittlement on contact with aluminum or steel, and it readily wets glass, quartz, and many surfaces, making cleanup challenging. It should be measured and loaded using non-reactive containers (e.g., polyethylene) and appropriate tools. Review the safety data sheet and handle in a well-ventilated area to avoid accidental spills or contamination.
This gallium evaporation material offers 99.999% purity in shot form (1-5 mm) for thermal deposition, but its low melting point (30°C) introduces handling and e-beam processing constraints.
Positive
- High Purity (99.999%): The 5N purity grade minimizes contamination during thin-film deposition, critical for semiconductor and optical coating applications.
- Optimized Shots Form: The 1-5 mm shot geometry facilitates uniform loading into thermal evaporation boats and crucibles, reducing source spitting.
Trade-offs
- Low Melting Point (30°C): The material's melting point near room temperature requires temperature-controlled storage to maintain solid form; handling at elevated ambient temperatures may cause liquefaction.
- E-Beam Evaporation Constraint: Low-power e-beam operation is recommended due to the low melting point; high-power e-beam may cause uncontrolled melting or droplet ejection.
