Barium Metal Evaporation Pieces 99.5% 1-10 mm ATOMFAIR®

Barium is an air-sensitive reactive metal that requires inert atmosphere storage and handling to prevent oxidation or pyrophoric reactions. The material must be compatible with Ta/Mo/W boats or crucibles and used only in controlled vacuum deposition environments.

• Inert atmosphere storage: Store under dry inert gas in a sealed container to avoid moisture and oxygen exposure.
• Safe handling environment: Handle only within a glovebox or inert gas enclosure to prevent spontaneous ignition in air.
• Crucible material compatibility: Use only tantalum, molybdenum, or tungsten boats or crucibles to avoid chemical reaction with molten barium.
• Vacuum system requirements: Evacuate the deposition chamber to high vacuum before heating to prevent oxidation of the melt.
• Moisture exclusion: Never expose barium to water or high humidity, as it reacts vigorously to produce hydrogen gas.

This process describes the safe transfer and loading of barium evaporation material into a vacuum deposition system. Proper procedures prevent air exposure and ensure uniform evaporation.

Required Equipment: Glovebox (inert atmosphere), Vacuum deposition system with high-vacuum pump, Ta, Mo, or W boat or crucible

1. Transfer to inert atmosphere
   Transfer the barium pieces from the shipping container into a glovebox maintained under dry inert gas to prevent oxidation.
2. Load crucible
   Load the required amount of barium pieces into a clean Ta, Mo, or W boat or crucible inside the glovebox.
3. Seal and transfer to chamber
   Seal the loaded crucible in an inert transfer vessel before moving it to the deposition chamber.
4. Mount and evacuate
   Mount the crucible in the deposition source and evacuate the chamber to the required high vacuum level for barium evaporation.
5. Heat to melting point
   Heat the crucible gradually to the melting point of 725°C while monitoring chamber pressure to avoid outgassing.
6. Deposit film
   Deposit the barium film using thermal or e-beam evaporation at the desired rate and thickness.

This Barium (Ba) 99.5% pieces evaporation material (1–10 mm) is supplied in inert packaging for thermal/resistive evaporation or low-power e-beam by RFQ, with defined purity and size range supporting laboratory thin-film deposition process matching.

Positive

• Defined material identity and purity: Barium (Ba) with 99.5% purity allows clear procurement matching to deposition process requirements, enabling standard, high-purity, or RFQ-controlled grading.
• Specified physical form and size range: Supplied as pieces with 1–10 mm sizing to facilitate source loading and evaporation review for thermal or e-beam methods.

Trade-offs

• Inert handling required: Barium is air-sensitive; the inert handling package is mandatory for storage and loading, requiring appropriate glovebox or sealed transfer infrastructure.
• E-beam evaporation requires RFQ: Low-power e-beam evaporation is not a standard configuration and must be requested via RFQ, adding lead time and coordination for that process route.
