Store under inert atmosphere to prevent oxidation. Use only tantalum, molybdenum, or tungsten boats for evaporation to avoid chemical incompatibility.
- Boat Material Compatibility: Use evaporation boats or crucibles made of tantalum, molybdenum, or tungsten to prevent reactive wetting or contamination of the molten barium.
- Inert Atmosphere Requirement: Maintain an inert gas environment during storage and handling to prevent reaction with moisture and oxygen.
- Particle Size Verification: Confirm that the 1-10 mm piece size fits within the boat cavity and does not cause uneven evaporation or spitting.
- Evaporation Parameter Calibration: Set the evaporation power and rate using the provided melting point (725°C) and Z-ratio (2.1) for accurate film thickness deposition.
Load barium pieces into an inert atmosphere glovebox and transfer to a tantalum boat. Evacuate the chamber and heat gradually to the melting point while monitoring deposition rate with a microbalance.
Required Equipment: Tantalum boat, Inert gas glovebox, Vacuum deposition system, Quartz crystal microbalance
- Store under inert gas
Store the barium material in an inert atmosphere glovebox immediately after opening the sealed inert package. - Load into boat
Load the barium pieces into a pre-cleaned tantalum boat using clean stainless steel forceps under inert gas. - Set evaporation parameters
Set the evaporation system parameters using the melting point of 725°C and Z-ratio of 2.1 for deposition rate calculation.
What is the significance of the Z-ratio of 2.1 for barium evaporation material in e-beam deposition?
The Z-ratio of 2.1 is a key parameter for calibrating quartz crystal microbalance (QCM) deposition rate monitors during e-beam evaporation. For Barium (Ba) Pieces with 99.9% purity and 1–10 mm size, this value enables accurate thickness control in low-power e-beam processes (by RFQ). The product also supports thermal/resistive evaporation using Ta, Mo, or W boats or crucibles, as specified in the technical datasheet.
What crucible or boat materials are compatible with barium evaporation pieces?
Barium evaporation material is compatible with tantalum (Ta), molybdenum (Mo), or tungsten (W) boats or crucibles, as stated in the product specifications. An inert handling package is also required to prevent oxidation during storage and loading. Buyers should confirm deposition source geometry and hardware compatibility before quoting.
What handling and storage precautions are required for barium evaporation pieces?
Barium (Ba) pieces require inert handling to avoid reaction with moisture or air; the product is supplied with an inert handling package. Buyers should review the safety data sheet (SDS), certificate of analysis, and shipment conditions prior to ordering. The material is supplied in 100g, 500g, or 1kg packs under research-grade laboratory protocols.
This Barium evaporation material (99.9% purity, 1–10 mm pieces) is designed for thermal or low-power e-beam deposition in vacuum systems, requiring inert handling to prevent oxidation. With a melting point of 725°C, density of 3.51 g/cm³, and Z-ratio of 2.1, it is suited for thin-film applications where source compatibility and pack size (100g–1kg) must be matched to deposition hardware and process scale.
Positive
- High purity 99.9% for consistent deposition: The 99.9% purity specification ensures minimal contamination in thin-film layers, critical for reproducible electronic or optical properties in research and development workflows.
- Multiple pack sizes for scalability: Available in 100g, 500g, and 1kg packages, allowing researchers to match material quantity to experimental or pilot production needs without excess waste or multiple orders.
Trade-offs
- Inert handling required for stability: The material is supplied with an inert handling package, indicating that barium must be protected from atmospheric exposure to prevent oxidation, requiring glovebox or inert gas workflows for storage and loading.
- Evaporation source compatibility must be verified: The product requires confirmation of boat or crucible material (Ta, Mo, W) and evaporation method (thermal or low-power e-beam) to ensure proper wetting, thermal contact, and film uniformity, as stated in the procurement checklist.
