This gold evaporation wire requires thermal/resistive evaporation using tungsten, molybdenum, or tantalum sources to prevent material incompatibility. Deposition parameters must account for the material's melting point of 1064°C and Z-ratio of 0.381 to achieve controlled film thickness.
- Source Material Compatibility: Use only W/Mo/Ta filament, basket, coil, or boat sources to avoid alloying or contamination during evaporation.
- Process Parameter Matching: Adjust deposition rate and power input based on the material's melting point and Z-ratio to maintain stable evaporation.
- Wire Geometry Constraint: Confirm that the 0.5 mm wire diameter fits the source coil or basket opening for secure loading.
- Melting Point Consideration: Limit power input to avoid exceeding the 1064°C melting point, which can damage the evaporation source.
What is the significance of the Z-ratio of 0.381 for this gold evaporation material in thermal evaporation processes?
The Z-ratio of 0.381 is a material-specific parameter used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance mismatch between the deposited film and the quartz crystal. This value is provided for gold (Au) at 99.99% purity, enabling accurate film thickness control during thermal/resistive evaporation.
Which evaporation source materials and geometries are compatible with this gold wire (99.99%, 0.5 mm dia.)?
This gold wire evaporation material is compatible with tungsten (W), molybdenum (Mo), or tantalum (Ta) sources in the form of filaments, baskets, coils, or boats. The 0.5 mm diameter wire is designed for easy loading into these thermal/resistive evaporation sources.
What is the melting point of this gold evaporation material and how does it influence the thermal evaporation process?
The melting point of this 99.99% pure gold evaporation material is 1,064°C. This relatively low melting point allows efficient thermal evaporation from standard resistive sources such as W/Mo/Ta boats and coils, with minimal power requirements and reduced risk of source contamination.
Gold (Au) evaporation wire with 99.99% purity and 0.5 mm diameter is evaluated for thermal resistive evaporation. The high purity and defined wire form support consistent thin-film deposition, but require careful source and process matching to achieve optimal results.
Positive
- High purity gold wire: 99.99% purity ensures minimal contamination in deposited thin films, critical for applications requiring precise electrical or optical properties.
- Defined wire diameter for source loading: Wire diameter of 0.5 mm facilitates consistent loading into thermal evaporation sources such as W/Mo/Ta filaments, baskets, coils, or boats.
Trade-offs
- Process compatibility verification required: Evaporation source hardware and process parameters (e.g., power, rate) must be matched to gold's melting point (1064°C) and Z-ratio (0.381) to achieve reproducible film thickness.
- Procurement specification confirmation needed: Buyers must confirm model, purity, form, wire diameter, pack size, and deposition-source compatibility before ordering to avoid mismatches in laboratory workflow.
