This material requires e-beam evaporation with water-cooled copper hearths and compatible liners. Process parameters must be matched to the material's melting point, density, and Z-ratio for proper deposition.
- Source Compatibility: The evaporation material is compatible with water-cooled copper e-beam hearths and liners made of graphite, Al2O3, BN, or tantalum.
- Particle Size Constraint: The supplied 3-6 mm pieces are sized for direct loading into e-beam evaporation sources without further size reduction.
- Melting Point Consideration: The material's melting point of 2,996 °C requires high-temperature e-beam evaporation capability.
- Z-Ratio Calibration: The Z-ratio of 0.262 must be used for quartz crystal microbalance thickness monitoring calibration.
- Process Matching: Evaporation source hardware and process route must be matched to material behavior, melting point, and film requirements.
What is the Z-ratio of Tantalum evaporation material and how does it affect quartz crystal microbalance calibration for film thickness monitoring?
The Tantalum (Ta) evaporation material has a Z-ratio of 0.262, as specified in the product's technical parameters. This value is critical for accurate quartz crystal microbalance (QCM) calibration because it corrects the acoustic impedance mismatch between the crystal and the deposited tantalum film, ensuring precise thickness monitoring during e-beam evaporation.
Which liner materials are compatible with Tantalum e-beam evaporation using a water-cooled copper hearth?
The compatible liner materials for Tantalum evaporation in a water-cooled copper e-beam hearth include graphite, Al2O3, BN, and Ta itself, as stated in the product specifications. This compatibility allows researchers to select liners that best match their thermal and chemical requirements for high-purity (99.99%) tantalum deposition at its melting point of 2,996°C.
What evaporation source hardware is required to handle the high melting point of Tantalum (2,996°C) during thin-film deposition?
A water-cooled copper e-beam hearth is the preferred evaporation source for Tantalum, as specified in the product details, to manage the extreme melting point of 2,996°C and density of 16.6 g/cm³. The water cooling prevents thermal damage to the hearth, while the e-beam provides the localized energy needed to vaporize the tantalum pieces (3–6 mm) without contaminating the high-purity (99.99%) material.
Tantalum evaporation material (99.99% purity, 3-6 mm pieces) is specified for e-beam deposition with a water-cooled copper hearth, offering high melting point (2,996°C) and density (16.6 g/cm³) for stable film growth. Buyers must verify deposition source compatibility and process parameters to match the material's properties.
Positive
- High purity 99.99%: The 99.99% purity specification minimizes contamination risks in thin-film deposition, ensuring consistent film quality for research-grade applications.
- Controlled piece size 3-6 mm: The specified piece size range facilitates uniform source loading and predictable evaporation behavior in e-beam systems, supporting reproducible deposition rates.
Trade-offs
- Deposition source compatibility required: The material is optimized for e-beam evaporation using a water-cooled copper hearth and compatible liners (graphite, Al2O3, BN, Ta); buyers must confirm their system's source geometry and liner compatibility before use.
- High melting point demands careful process matching: With a melting point of 2,996°C and density of 16.6 g/cm³, the evaporation source hardware and process parameters (e.g., power, beam sweep) must be precisely matched to the material's thermal behavior to avoid process instability or hardware damage.
