Tantalum evaporation material pieces require a water-cooled copper e-beam hearth with a compatible liner (graphite, Al2O3, BN, or Ta) to withstand the high melting point (2996°C) and prevent contamination. The 1-3 mm piece size ensures stable source loading and proper evaporation, while the 99.95% purity supports high-quality thin-film deposition.
- Source Compatibility: Use a water-cooled copper e-beam hearth with a graphite, Al2O3, BN, or Ta liner to handle the high melting point and avoid contamination.
- Size Requirement: The 1-3 mm piece size is required for consistent source loading and to prevent spitting or clogging during evaporation.
- Purity Impact: The 99.95% purity minimizes impurities in the deposited film, which is critical for electronic and optical applications.
- Deposition Monitoring: The Z-ratio of 0.262 must be used for accurate deposition rate monitoring with a quartz crystal microbalance.
What is the significance of the Z-ratio value of 0.262 for Tantalum e-beam evaporation material?
The Z-ratio of 0.262 is a material-specific parameter provided for Tantalum (Ta) to calibrate the thickness monitor during e-beam evaporation. This value is essential for accurate deposition rate control and film thickness measurement when using the recommended water-cooled copper e-beam hearth with compatible liners.
Which liner materials are compatible with Tantalum evaporation in an e-beam system?
Compatible liner materials for this Tantalum evaporation material include graphite, alumina (Al₂O₃), boron nitride (BN), and tantalum (Ta) itself. These liners are specified to withstand the high melting point of 2,996°C and are used with a water-cooled copper e-beam hearth.
How does the pack size affect the cost per gram for Tantalum evaporation material?
Based on the indicated price tiers, the cost per gram decreases with larger pack sizes: 25g at $13.20/g, 100g at $7.50/g, 500g at $4.00/g, and 1kg at $2.80/g. The 1kg pack offers the most economical price per gram for bulk procurement, while the 25g pack allows low-volume testing.
This tantalum evaporation material (99.95% purity, 1-3 mm pieces) is designed for e-beam deposition of refractory metal films, with defined size distribution and purity to support reproducible thin-film growth.
Positive
- High Purity 99.95%: The 99.95% purity specification enables direct comparison with standard and high-purity grades, ensuring reproducible film composition in deposition processes.
- Optimized Piece Size 1-3 mm: The 1-3 mm piece size facilitates consistent loading into e-beam evaporation sources, supporting uniform evaporation rates.
Trade-offs
- High Melting Point Requirement: With a melting point of 2,996 °C, this material requires e-beam evaporation equipment capable of reaching and sustaining high temperatures, typically with water-cooled copper hearths.
- Compatible Liner Required: Evaporation source must use compatible liners (graphite, Al2O3, BN, or Ta) to prevent contamination and ensure stable evaporation; not all e-beam systems are pre-configured for these liners.
