This lead evaporation material is intended for thermal/resistive evaporation under vacuum using compatible W/Mo/Ta filament or boat sources. Deposition performance requires careful matching of material properties including melting point, density, and Z-ratio to the process parameters.
- Deposition Source Compatibility: The evaporation material must be used with a compatible thermal evaporation source such as W, Mo, or Ta filament, basket, coil, or boat.
- Process Parameter Matching: The material's melting point, density, and Z-ratio must be considered when setting evaporation parameters and deposition rate monitoring.
- Handling and Safety Requirements: The safety data sheet and certificate must be reviewed for appropriate handling precautions due to the toxicity of lead.
- Physical Form Constraint: The wire diameter imposes constraints on the evaporation source geometry and loading method.
What is the significance of the Z-Ratio of 1.13 for lead wire in thermal evaporation?
The Z-Ratio of lead is stated as 1.13 in the technical specifications for this wire evaporation material (AF-PBWIR-4N2P0MM). In thermal evaporation processes using quartz crystal microbalance (QCM) thickness monitoring, the Z-Ratio corrects for acoustic impedance mismatch between the deposited film and the quartz crystal; a value of 1.13 indicates that lead's acoustic properties differ slightly from ideal (Z=1), requiring tooling factor calibration to achieve accurate film thickness control during deposition runs using this wire form.
What boat or filament materials are recommended for evaporating lead wire with a diameter of 2.0 mm?
For thermal/resistive evaporation of this lead wire (diameter 2.0 mm), compatible evaporation sources include tungsten (W), molybdenum (Mo), or tantalum (Ta) filaments, baskets, coils, or boats as specified in the product description. These refractory metals withstand the high temperatures needed to melt lead (melting point ~328°C) without contaminating the evaporant; the wire diameter of 2.0 mm is suitable for loading into standard coil windings or boat cavities used in typical thermal evaporators.
What safety considerations are critical when handling lead evaporation material with a melting point of 328°C?
Lead has a relatively low melting point of approximately 328°C as listed in the specifications for this wire evaporation material; at typical evaporation temperatures above its melting point it generates toxic lead vapor that poses serious inhalation hazards. Proper engineering controls such as fume extraction within the vacuum chamber exhaust system are essential; operators must review the safety data sheet provided by Atomfair LLC before handling this material and use appropriate personal protective equipment including gloves and respiratory protection during loading and maintenance procedures.
Lead (Pb) evaporation wire with 99.99% purity and 2.0 mm diameter offers high material purity and broad compatibility with thermal evaporation sources, but requires careful source geometry verification.
Positive
- High purity 99.99%: This lead wire is specified at 99.99% purity, enabling reproducible thin-film deposition with minimal contamination for research-grade applications.
- Broad evaporation source compatibility: Compatible with W/Mo/Ta filament, basket, coil, or boat sources, allowing integration into common thermal resistive evaporation systems.
Trade-offs
- Fixed wire diameter requires source geometry check: The wire diameter is fixed at 2.0 mm; buyers must confirm that this dimension matches their deposition source geometry to ensure proper loading and evaporation.
