This platinum evaporation material requires thermal/resistive evaporation under vacuum using refractory metal sources such as tungsten, molybdenum, or tantalum. The wire form must be loaded into the source without contamination to maintain the specified 99.999% purity during deposition.
- Evaporation Source Compatibility: Use only W/Mo/Ta filament, basket, coil, or boat sources to avoid material incompatibility and source degradation.
- Vacuum Requirement: Perform all evaporation steps in a high-vacuum chamber to prevent oxidation and ensure film adhesion.
- Wire Handling: Handle the 0.5 mm diameter wire with clean tools or gloves to prevent surface contamination that affects film purity.
- Z-Ratio Calibration: Use the Z-Ratio of 0.245 for quartz crystal monitor calibration to accurately control film thickness during deposition.
What is the significance of the Z-Ratio of 0.245 for platinum wire in thermal evaporation processes?
The Z-Ratio of 0.245 is used to calibrate quartz crystal microbalance (QCM) thickness monitors during thermal evaporation of this platinum wire (99.999%, dia. 0.5 mm). This value accounts for the acoustic impedance mismatch between platinum and the quartz crystal sensor; accurate Z-Ratio input ensures correct film thickness measurement while an incorrect value can lead to significant deposition errors.
Which evaporation source materials are compatible with this platinum wire?
This platinum wire (99.999%, dia. 0.5 mm) is compatible with thermal/resistive evaporation using tungsten (W), molybdenum (Mo), or tantalum (Ta) filaments, baskets, coils, or boats. These refractory metals withstand the high melting point of platinum (1,772 °C) without contaminating the deposit.
What storage and handling considerations apply to high-purity platinum wire for evaporation?
As a precious metal with density of 21.45 g/cm³ and wire diameter of only 0.5 mm, this platinum wire should be stored in its original packaging to prevent contamination and mechanical damage. Handle with clean gloves to avoid introducing impurities that could compromise the 99.999% purity grade during loading into evaporation sources.
Platinum (Pt) evaporation wire with 99.999% purity and 0.5 mm diameter is supplied as a pure-metal wire for thermal/resistive evaporation using W/Mo/Ta filament, basket, coil, or boat sources; its 1,772 °C melting point and 0.245 Z-ratio are specified to guide source matching and process review.
Positive
- High-purity platinum wire: The 99.999% purity specification reduces background metallic contamination during evaporation, supporting reproducible film composition in vacuum deposition workflows.
- Defined wire geometry for source loading: The 0.5 mm wire form is explicitly matched to W/Mo/Ta filament, basket, coil, or boat sources, simplifying evaporation-source loading and process planning.
Trade-offs
- High-temperature source compatibility required: Platinum's 1,772 °C melting point requires the stated refractory-metal source hardware and a process route matched to the material's melting behavior.
- Pre-quote configuration verification required: Model, purity, form, diameter, pack size, certificate requirements, and shipment conditions must be confirmed before quotation, adding a procurement review step for buyers.
