Tungsten evaporation pieces require e-beam deposition with a water-cooled copper hearth and a compatible liner to maintain purity and process stability. The material's high melting point and specific Z-ratio dictate precise thermal management and film thickness calibration.
- Deposition Source Compatibility: The material must be evaporated using an e-beam source with a water-cooled copper hearth and a liner made of graphite, Al2O3, BN, or Ta to prevent contamination.
- Thermal Management Requirement: The melting point of 3410°C requires the evaporation source to sustain high temperatures without degradation or thermal runaway.
- Film Thickness Calibration: The Z-ratio of 0.163 must be entered into the quartz crystal monitor to ensure accurate film thickness measurement during deposition.
- Purity Handling Precautions: The 99.99% purity grade requires storage in a clean, dry environment and handling with clean tools to avoid surface contamination.
- Physical Form Loading Considerations: The 3–6 mm pieces may require careful arrangement in the hearth to prevent bridging and ensure uniform evaporation flux.
What evaporation method and liner materials are recommended for tungsten pieces of 3–6 mm size?
E-beam evaporation is the preferred method for this tungsten material, using a water-cooled copper hearth. Compatible liner materials include graphite, Al2O3, BN, and Ta, as specified in the product description.
What are the key physical properties of this tungsten evaporation material relevant to deposition?
The material has a melting point of 3,410°C, a density of 19.35 g/cm³, and a Z-ratio of 0.163. These parameters are critical for process control, such as crucible selection and quartz crystal monitor calibration during thin-film deposition.
How does the 99.99% purity grade affect the suitability of tungsten evaporation pieces for research-grade thin-film applications?
The 99.99% purity specification ensures minimal contamination during evaporation, making the material suitable for high-quality thin-film deposition in research and development settings. This purity level is explicitly listed for the product.
Tungsten (W) evaporation material in pieces (3-6 mm) with 99.99% purity, offering high melting point (3410°C) and density (19.35 g/cm³) for e-beam evaporation. The Z-ratio of 0.163 requires careful thickness monitoring, and deposition source compatibility must be verified before use.
Positive
- High purity and defined physical form: 99.99% purity and 3-6 mm pieces ensure consistent evaporation behavior and film quality for research-grade thin-film deposition.
- Compatible with high-temperature e-beam evaporation: Melting point of 3410°C and density of 19.35 g/cm³ support use with water-cooled copper e-beam hearth and graphite/Al2O3/BN/Ta liners, enabling reliable deposition of refractory metal films.
Trade-offs
- Requires precise thermal management and process control: High melting point and density, combined with a Z-ratio of 0.163, demand accurate e-beam power regulation and thickness monitoring to avoid material consumption errors or source damage.
- Deposition source geometry must be verified: The 3-6 mm piece size may not fit all evaporation sources; confirmation of source compatibility and size range is required before ordering to avoid loading issues.
