This gallium evaporation material requires deposition using a Mo/W/Ta boat or graphite/alumina crucible within a vacuum thin-film deposition system. The material's low melting point of 30°C necessitates careful temperature control during thermal resistive evaporation to avoid premature melting or contamination.
- Evaporation Source Compatibility: Use only Mo/W/Ta boat or graphite/alumina crucible for evaporation; incompatible materials may cause contamination or crucible damage.
- Melting Point Sensitivity: The gallium material melts at 30°C, requiring temperature control below this point during storage and handling to prevent liquefaction.
- Particle Size Specification: The 1-5 mm pieces are sized for source loading; ensure the source geometry accommodates this size range.
- Vacuum Deposition Requirement: All evaporation must be performed under vacuum conditions to achieve proper thin-film deposition.
- Procurement Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before quotation.
Why is gallium evaporation material supplied as pieces despite its melting point of 30°C?
Gallium has a melting point of 30°C, meaning it will liquefy near room temperature. The pieces (1-5 mm) are supplied to allow precise loading into evaporation sources such as Mo/W/Ta boats or graphite/alumina crucibles before melting. Once heated, the material melts and uniformly wets the source surface, enabling controlled evaporation.
Which boat and crucible materials are compatible with gallium evaporation?
The source specifies that thermal/resistive evaporation is preferred, with low-power e-beam as an option. Compatible boat materials include molybdenum, tungsten, or tantalum, and compatible crucibles include graphite and alumina. These materials resist wetting and reaction with liquid gallium, ensuring stable deposition.
What precautions are required when handling gallium evaporation material due to its low melting point?
Gallium melts at approximately 30°C, so it may be liquid in warm environments. The material should be handled in a controlled environment to avoid spillage and contamination of surfaces. The source recommends reviewing the certificate and safety data sheet for specific handling, storage, and shipment conditions before use.
Gallium (Ga) evaporation material (99.999%, 1-5 mm pieces) offers high purity for demanding thin-film deposition, with a low melting point (30°C) enabling low-power thermal evaporation. However, its low melting point necessitates temperature-controlled storage, and it requires specific boat/crucible materials (Mo/W/Ta or graphite/alumina) for compatible source hardware.
Positive
- High purity (99.999%): Minimizes thin-film contamination for demanding optical and electronic applications.
- Low melting point for low-power evaporation: The 30°C melting point allows efficient thermal evaporation at reduced power, lowering thermal load on substrates.
Trade-offs
- Temperature-sensitive storage required: With a melting point of 30°C, the material may liquefy if stored above room temperature, requiring climate-controlled conditions.
- Specific crucible/boat compatibility: Evaporation requires Mo/W/Ta boat or graphite/alumina crucible, limiting source hardware options and requiring verification.
