This platinum wire evaporation material requires careful matching to deposition source hardware and process parameters. The 99.99% purity grade and wire form demand contamination-free handling and vacuum infrastructure for thin-film deposition.
- Deposition Source Compatibility: The evaporation source hardware must be selected from W/Mo/Ta filament, basket, coil, or boat types to match the wire form and diameter.
- Process Route Matching: The thermal/resistive evaporation process route must be matched to the material's melting point (1,772 °C), density (21.45 g/cm³), and Z-ratio (0.245) for consistent film deposition.
- Purity and Handling: The 99.99% purity grade requires contamination-free handling during loading and storage to maintain film quality.
- Infrastructure Requirements: Vacuum thin-film deposition equipment is required for thermal evaporation of this material.
How does the Z-ratio of 0.245 affect film thickness monitoring during thermal evaporation of this platinum wire?
The Z-ratio of 0.245 is a material-specific parameter used in quartz crystal microbalance thickness monitoring systems. This value, combined with the density of 21.45 g/cm³, must be programmed into the deposition controller to correct for acoustic impedance mismatch and ensure accurate film thickness measurement. Users should verify that their controller supports this Z-ratio or adjust tooling factors accordingly.
What filament or boat materials are compatible with this 0.5 mm platinum wire for thermal evaporation?
This platinum wire is specified for thermal/resistive evaporation using tungsten (W), molybdenum (Mo), or tantalum (Ta) filaments, baskets, coils, or boats. The 0.5 mm wire diameter is suitable for loading into these sources, but buyers should confirm that the source geometry can accommodate the wire length and diameter for uniform heating and evaporation.
What documentation is provided with this platinum evaporation material for laboratory safety and procurement compliance?
The product listing states that a certificate of analysis, safety data sheet (SDS), shipment condition details, and export requirements can be reviewed against laboratory use requirements. Buyers should request these documents before quotation to ensure compliance with institutional safety protocols and import regulations for high-purity precious metals.
Evaluation of this Platinum wire evaporation material reveals 99.99% purity and 0.5 mm diameter suited for thermal/resistive evaporation, with a melting point of 1,772°C and Z-ratio of 0.245 requiring careful process control.
Positive
- High Purity 99.99% for Deposition: The 99.99% purity specification minimizes contamination in thin-film layers, critical for reproducible electronic or optical coatings.
- Standard Wire Form and Diameter: The 0.5 mm diameter wire form is compatible with W/Mo/Ta filament, basket, coil, or boat sources, simplifying source loading in thermal evaporation systems.
Trade-offs
- High Melting Point Requires Robust Source: With a melting point of 1,772°C, this material demands high-temperature evaporation sources and may cause thermal stress on conventional boats or filaments.
- Low Z-Ratio Demands Thickness Calibration: A Z-ratio of 0.245 indicates that the crystal monitor will overestimate film thickness, requiring tooling factor adjustments for accurate deposition control.
