This material is a high-purity molybdenum wire intended for electron-beam evaporation in vacuum thin-film deposition. Deposition source compatibility and process parameters must be matched to the material's melting point and Z-ratio to achieve consistent film quality.
- Evaporation Source Compatibility: Use a water-cooled e-beam hearth or W/Ta support; thermal evaporation is only acceptable for thin charges or qualified setups.
- Wire Form and Geometry: Confirm the 0.5 mm wire diameter is compatible with the source feed mechanism and crucible geometry.
- Deposition Process Control: The high melting point of 2,617°C and Z-ratio of 0.257 require careful selection of e-beam power and sweep parameters to achieve uniform evaporation.
- Pre-Order Verification: Verify model, purity, form, size, and pack size, and confirm deposition-source compatibility before quotation.
Why is the Z-ratio of 0.257 important for controlling deposition rate when using molybdenum wire in e-beam evaporation?
The Z-ratio (0.257) is a material-specific correction factor used in quartz crystal microbalance (QCM) monitoring to accurately determine film thickness and deposition rate. For molybdenum, this value directly affects the calibration of the crystal monitor, and using the correct Z-ratio (0.257) ensures precise rate control and reproducible film thickness during e-beam evaporation. The product specification explicitly lists Z-Ratio: 0.257, confirming it is a critical parameter for process engineers.
What deposition source configurations are compatible with 0.5 mm molybdenum wire for thin-film evaporation?
The 0.5 mm molybdenum wire is designed for use with a water-cooled e-beam hearth as the preferred evaporation source, with tungsten or tantalum support available by RFQ. Thermal evaporation is only suitable for thin charge or qualified setups, as stated in the product description. Confirming source geometry and compatibility with the buyer's deposition hardware is a mandatory procurement check before quotation.
What documentation and verification steps are required when procuring 99.99% molybdenum wire for laboratory thin-film deposition?
Procurement must include confirmation of the certificate of analysis, safety data sheet, shipment conditions, and export requirements to ensure the material meets laboratory-use standards. The product description emphasizes reviewing these documents against specific application needs, and verifying the model, purity (99.99%), form (wire), and wire diameter (0.5 mm) is mandatory before placing an order. This ensures material traceability and compatibility with deposition process requirements.
Molybdenum evaporation wire (99.99%, 0.5 mm dia) is supplied as a variable-pack-size pure metal source for e-beam evaporation, with a melting point of 2,617°C and Z-ratio of 0.257, requiring source compatibility verification for thermal evaporation use.
Positive
- High-purity wire form for evaporation: 99.99% purity and 0.5 mm diameter wire ensure consistent deposition and source loading for thin-film applications.
- E-beam evaporation optimization: Preferred for e-beam evaporation with water-cooled hearth, supporting controlled deposition of high-melting-point molybdenum.
Trade-offs
- Thermal evaporation limited: Thermal evaporation is only suitable for thin charges or qualified setups, limiting its use in standard thermal boats.
- Source compatibility required: Buyers must confirm deposition source geometry, hearth type, and support configuration before ordering to avoid operational mismatch.
