How does the Z-ratio of 0.245 for platinum wire affect thickness monitoring during thermal evaporation?
The Z-ratio of 0.245 is used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness measurement during thermal evaporation. This value must be entered into the deposition controller to correct for acoustic impedance mismatch between the quartz crystal and the deposited platinum film.
What evaporation source materials are compatible with this 1.0 mm diameter platinum wire?
This platinum wire is compatible with thermal/resistive evaporation using tungsten (W), molybdenum (Mo), or tantalum (Ta) filaments, baskets, coils, or boats. The 1.0 mm diameter wire form facilitates easy loading and consistent evaporation from these common source geometries.
What is the melting point and density of this platinum wire, and how do they influence evaporation process parameters?
The melting point of this platinum wire is 1,772 °C and its density is 21.45 g/cm³. These parameters dictate the power requirements and deposition rate; the high melting point requires robust heating elements and sufficient power supply to achieve evaporation temperatures.
This 99.999% pure platinum wire in 1.0 mm diameter is designed for thermal/resistive evaporation in thin-film deposition, with a 1772°C melting point and 0.245 Z-ratio requiring careful source matching and thickness monitor calibration.
Positive
- High purity 99.999% platinum wire: The 99.999% purity minimizes film contamination, critical for research-grade thin-film applications.
- Precise wire diameter for source loading: The 1.0 mm wire form facilitates consistent loading into thermal evaporation sources such as W/Mo/Ta filaments, baskets, coils, or boats.
Trade-offs
- High melting point requires adequate source power: With a melting point of 1772°C, the evaporation source must be capable of sustaining sufficient temperature for efficient deposition, which may limit compatibility with low-power systems.
- Z-ratio correction needed for thickness monitoring: The Z-ratio of 0.245 requires calibration of quartz crystal thickness monitors to ensure accurate film thickness control during deposition.
