This material requires compatible evaporation source hardware such as Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner. The melting point of 1064°C, density of 19.32 g/cm³, and Z-ratio of 0.381 must be accounted for in deposition rate calibration and process design.
- Deposition Source Compatibility: Use only with thermal/resistive or e-beam evaporation systems using Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners.
- Material Selection Verification: Confirm model, purity, form, size range, and pack size before quotation to ensure compatibility with deposition source geometry and process requirements.
- Deposition Process Matching: Match the evaporation source hardware and process route to the material's melting point, density, and film requirements to avoid contamination or failed deposition.
- Certificate and Documentation Review: Review certificate of analysis, safety data sheet, and shipment conditions against laboratory use requirements prior to handling.
- Pack Size Selection: Select the pack size (1g to 100g) based on the required quantity and deposition source geometry to minimize waste and ensure consistent loading.
Why is the Z-ratio of 0.381 important for gold evaporation in thin-film deposition?
The Z-ratio of 0.381 is a material-specific acoustic impedance factor used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness monitoring during e-beam evaporation. Applying the correct Z-ratio for gold ensures the measured thickness matches the actual deposited film, which is critical for achieving precise optical or electrical properties in the final device.
What boat and liner materials are compatible with thermal and e-beam evaporation of gold pellets?
For thermal/resistive evaporation, gold pellets (99.999%, 1-3 mm) can be loaded into molybdenum, tungsten, or tantalum boats. For e-beam evaporation, a water-cooled copper hearth lined with graphite or alumina is recommended to prevent alloying and contamination at the 1,064°C melting point of gold.
How does the 1-3 mm pellet size of this gold evaporation material influence source loading and deposition uniformity?
The 1-3 mm pellet size is optimized for consistent loading into thermal boats and e-beam hearths, reducing void spaces that could cause uneven evaporation or spitting. This size range also promotes uniform melting and stable vapor flux, which is essential for reproducible thin-film thickness across the substrate.
This Gold (Au) evaporation material, supplied as 99.999% pure 1-3 mm pellets, is suitable for thermal/resistive or e-beam deposition. The variable pack sizes accommodate different scale requirements, but users must ensure compatibility with their specific evaporation source hardware.
Positive
- Ultra-high purity 99.999%: Gold pellets with 99.999% purity minimize contamination in thin-film deposition, enabling high-quality films for research and advanced applications.
- Multiple pack size options: Available in 1g to 100g packs, allowing users to order exactly the quantity needed for small-scale R&D or larger production runs.
Trade-offs
- Specific hardware compatibility required: Deposition requires Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner; users must verify source compatibility before ordering.
- Pellet size constraints for source loading: The 1-3 mm pellet size may not fit all evaporation sources; confirmation of source geometry is necessary to avoid loading issues.
