This titanium pellet material requires e-beam evaporation using a water-cooled copper hearth with compatible liners. The material's melting point, density, and Z-ratio must be factored into process parameter selection to achieve optimal deposition.
- Evaporation Source Compatibility: Use only with a water-cooled copper e-beam hearth and liners made of graphite, Al2O3, BN, or Ta to avoid contamination.
- Preferred Evaporation Method: E-beam evaporation is the recommended method; alternative thermal evaporation may not achieve sufficient vapor pressure.
- Material Property Constraints: The melting point of 1660°C, density of 4.5 g/cm³, and Z-ratio of 0.628 must be used to calibrate deposition rate and thickness monitor.
- Pellet Size Handling: The 1-3 mm pellet size is optimized for consistent feeding into the e-beam hearth; verify hopper or source geometry accommodates this size range.
- Pre-Use Verification: Confirm that the deposition source geometry, liner material, and vacuum system are compatible with titanium evaporation before loading.
How does the Z-ratio of 0.628 affect thickness monitoring during e-beam evaporation of these titanium pellets?
The Z-ratio of 0.628 is used to calibrate the quartz crystal microbalance (QCM) for accurate film thickness measurement during deposition. This value accounts for the acoustic impedance mismatch between the titanium film and the quartz crystal, ensuring precise rate and thickness control. The specified Z-ratio is provided for the 99.9% pure titanium pellets to support reproducible thin-film deposition.
What liner materials are compatible with e-beam evaporation of these titanium pellets and why?
The compatible liner materials are graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum), as stated for use with a water-cooled copper e-beam hearth. These materials are selected because they can withstand the high melting point of titanium (1660°C) and minimize chemical reaction or contamination with the molten titanium. The choice depends on the specific deposition requirements and source geometry.
What is the significance of the 1-3 mm pellet size for e-beam evaporation of titanium?
The 1-3 mm pellet size is designed to ensure consistent feeding and uniform melting in e-beam evaporation sources. This size range prevents issues like bridging from smaller particles or incomplete melting from larger chunks, and is compatible with standard water-cooled copper hearths. The specified form factor supports reliable, reproducible thin-film deposition.
This Titanium (Ti) evaporation material is supplied as 99.9% pure pellets in 1-3 mm size, suitable for E-beam evaporation in water-cooled copper hearths with compatible liners; buyers must verify deposition source geometry and process parameters before ordering.
Positive
- Defined Material Identity and Purity: Titanium (Ti) with 99.9% purity ensures clear procurement matching and deposition process consistency for thin-film applications.
- Specified Pellet Form and Size: Pellets 1-3 mm size range facilitates loading into water-cooled copper e-beam hearths with compatible liners, supporting E-beam evaporation workflows.
Trade-offs
- Deposition Source Compatibility Verification Required: Buyers must confirm that the pellet size, purity, and form match their specific deposition source geometry and liner material (graphite, Al2O3, BN, Ta) before ordering.
- Process Matching and Infrastructure Dependencies: Evaporation source hardware and process route must be matched to the material's melting point (1,660°C), density (4.5 g/cm³), and Z-ratio (0.628) to achieve desired film properties.
