Palladium evaporation wire requires thermal/resistive evaporation using refractory metal sources. The Z-ratio of 0.357 must be applied for accurate deposition rate monitoring.
- Source Compatibility: Use only tungsten, molybdenum, or tantalum filament, basket, coil, or boat sources for thermal evaporation.
- Wire Loading: The 1.0 mm diameter wire is compatible with standard refractory metal source configurations.
- Z-Ratio Application: Set the Z-ratio to 0.357 in the quartz crystal microbalance controller for correct thickness measurement.
- Melting Point: Heat the source to a temperature exceeding 1,554°C under vacuum to achieve evaporation.
What is the significance of the Z-ratio of 0.357 for palladium wire in thermal evaporation processes?
The Z-ratio of 0.357 indicates the acoustic impedance of palladium relative to quartz crystal microbalance sensors, which must be programmed into the deposition controller for accurate film thickness monitoring during thermal evaporation. Given palladium's melting point of 1,554 °C and density of 12.02 g/cm³, using the correct Z-ratio ensures that the rate and thickness readings correspond to the actual deposited mass.
Which evaporation source materials are compatible with 99.999% palladium wire of 1.0 mm diameter?
This palladium wire is compatible with thermal/resistive evaporation using tungsten (W), molybdenum (Mo), or tantalum (Ta) filaments, baskets, coils, or boats. The 1.0 mm wire diameter is suitable for loading into these source geometries; however, buyers should confirm that their specific source geometry and wire feed mechanism can accommodate this diameter before ordering.
How should 99.999% palladium wire be stored and handled to maintain its high purity before deposition?
To preserve the 99.999% purity specification, the palladium wire should be stored in a clean, dry environment away from airborne contaminants and moisture. Handling must be performed with clean gloves or tweezers to avoid surface contamination that could introduce impurities into the deposited film during thermal evaporation.
This palladium wire (99.999% purity, 1.0 mm diameter) is engineered for thermal evaporation in vacuum thin-film deposition, requiring careful matching of source hardware (W/Mo/Ta filament, basket, coil, or boat) and process parameters to achieve consistent film quality.
Positive
- High purity reduces contamination: The 99.999% purity specification minimizes trace element incorporation into deposited films, enabling reliable comparison against standard or high-purity grades for demanding applications.
- Wire form with defined diameter: Wire form with 1.0 mm diameter provides consistent source loading geometry for thermal evaporation, supporting reproducible deposition rates and simplifying process setup.
Trade-offs
- Requires hardware compatibility check: Evaporation source hardware (W/Mo/Ta filament, basket, coil, or boat) and process route must be matched to the material's melting point (1554 °C) and film requirements, mandating pre-order verification of deposition system compatibility.
- Process parameters need optimization: The high melting point and Z-ratio (0.357) demand careful control of evaporation rate and substrate temperature, increasing the need for process development to achieve target film properties.
