This tantalum oxide evaporation material requires E-beam evaporation with a graphite, Al2O3, or BN liner or a W/Mo/Ta boat for optimal deposition performance. The tableted form's melting point, density, and Z-ratio must be considered during source setup and film thickness monitoring.
- Evaporation Source Compatibility: Use E-beam evaporation with a graphite, Al2O3, or BN liner or a W/Mo/Ta boat to avoid material contamination and ensure proper vaporization.
- Preferred Evaporation Method: E-beam evaporation is the preferred method; thermal evaporation is available only by request and may require source hardware adjustments.
- Melting Point Consideration: The melting point of 1,872°C requires sufficient power capacity in the evaporation source to achieve full vaporization without overheating.
- Z-Ratio Effect on Thickness Monitoring: The Z-ratio of 0.3 must be entered into the quartz crystal microbalance controller for accurate film thickness deposition rate measurement.
- Physical Form Matching: The 6 mm tablet diameter must be compatible with the crucible or boat cavity dimensions to ensure stable loading and even heating.
How does the Z-Ratio of 0.3 affect process control during Ta2O5 evaporation?
The Z-Ratio of 0.3 is used for quartz crystal microbalance (QCM) calibration to correct for acoustic impedance mismatch between the crystal and the deposited material. A lower Z-Ratio, such as 0.3, indicates a higher mismatch, requiring a larger tooling factor adjustment to maintain accurate thickness monitoring. The product's density of 8.2 g/cc and melting point of 1,872°C further influence evaporation rate and film stoichiometry, so the QCM parameters must be set accordingly for reproducible thin-film deposition.
Can Ta2O5 tablets be used in thermal evaporation boats, or only E-beam hearths?
E-beam evaporation is the preferred method for these Ta2O5 tablets, with performance rated as Good. Thermal evaporation is possible but requires a request for quotation (RFQ) to evaluate compatibility with available boat materials such as W, Mo, or Ta. The high melting point of 1,872°C and the 6 mm tablet form may necessitate specialized thermal sources or crucible liners, so users should confirm deposition-source geometry and hardware before ordering.
What are the recommended storage and handling practices for Ta2O5 evaporation material to maintain 99.95% purity?
The product listing recommends reviewing the safety data sheet (SDS) and confirming shipment conditions for handling guidelines. As a high-purity metal oxide, standard precautions for fine powders apply: store in a dry, sealed container to prevent moisture absorption and avoid contamination. The 99.95% purity grade requires careful handling in a clean laboratory environment, and buyers should consult the provided documentation for export requirements and storage instructions.
Tantalum Oxide (Ta2O5) evaporation material in 6 mm tablet form at 99.95% purity is evaluated for E-beam evaporation with good performance, requiring specific liner or boat materials (graphite/Al2O3/BN or W/Mo/Ta) and a melting point of 1,872°C with density 8.2 g/cm³ and Z-ratio 0.3, which influences deposition rate monitoring.
Positive
- High-purity 99.95% Ta2O5 tablet: The 99.95% purity specification supports consistent thin-film stoichiometry and reduces contamination risk in optical or dielectric layer deposition.
- Defined 6 mm tablet form factor: The 6 mm tablet size is compatible with standard E-beam hearths and boat sources, enabling reproducible loading and evaporation in vacuum systems.
Trade-offs
- E-beam evaporation preferred method: Thermal evaporation requires RFQ confirmation, limiting direct process flexibility; users must verify source compatibility with graphite/Al2O3/BN liners or W/Mo/Ta boats.
- Z-ratio of 0.3 affects rate control: The low Z-ratio of 0.3 necessitates careful calibration of quartz crystal microbalance (QCM) monitors to avoid film thickness errors during deposition.
