Zirconium (Zr) evaporation material in piece form requires e-beam evaporation with a water-cooled copper hearth and compatible liner materials such as graphite, Al2O3, BN, or Ta. The material's melting point of 1852°C and Z-ratio of 0.6 must be considered when setting deposition parameters to achieve consistent film thickness.
- Deposition Source Compatibility: Use only with water-cooled copper e-beam hearths and liners made of graphite, Al2O3, BN, or Ta to prevent contamination and ensure thermal management.
- Material Form and Size: The 1-3 mm piece size is designed for uniform loading in e-beam crucibles and must be confirmed against source geometry before use.
- Purity Requirement: The 99.95% purity specification minimizes film contamination and requires handling in clean conditions to maintain integrity.
- Process Parameter Matching: Melting point (1852°C) and Z-ratio (0.6) directly influence evaporation rate and film thickness control; verify these against your deposition system's capabilities.
- Pre-Use Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before opening or using the material.
How does the 1-3 mm piece size of Zr evaporation material affect deposition rate and uniformity in e-beam evaporation?
The 1-3 mm piece size is selected to balance source loading density and consistent evaporation. For e-beam evaporation with a water-cooled copper hearth, larger pieces reduce surface area and may require higher beam power, while smaller pieces risk spitting. The specified range is typical for stable e-beam evaporation, and the Z-ratio of 0.6 indicates a moderate acoustic impedance mismatch for accurate quartz crystal monitoring.
What liner materials are compatible with Zr evaporation in an e-beam system?
Compatible liner materials include graphite, Al2O3, BN, and Ta. These are chosen for thermal stability and low reactivity with molten zirconium at its melting point of 1,852°C. The water-cooled copper e-beam hearth is preferred to prevent crucible contamination, and the product is optimized for e-beam evaporation sources.
What is the melting point of Zr evaporation material and how does it influence source selection?
The melting point of Zr is 1,852°C, with a density of 6.49 g/cm³. This high melting point requires an e-beam evaporation source with a water-cooled copper hearth and compatible liners such as graphite or Al2O3 to withstand the temperature without degrading. Thermal evaporation using tungsten boats is not recommended as the temperature may exceed boat material limits.
Zirconium (Zr) evaporation material at 99.95% purity in 1-3 mm pieces offers high purity and defined particle size for e-beam deposition, but requires compatible hardware and careful thermal management due to its high melting point.
Positive
- High purity 99.95%: The 99.95% purity specification ensures minimal contamination for reproducible thin-film deposition in research applications.
- Optimized particle size 1-3 mm: The pieces sized 1-3 mm are designed for efficient loading and stable evaporation in e-beam sources, reducing spitting and source bridging.
Trade-offs
- Requires compatible e-beam hardware: Optimal use requires a water-cooled copper e-beam hearth with graphite/Al2O3/BN/Ta liners; incompatible with other evaporation methods without validation.
- High melting point operational constraint: With a melting point of 1852°C and a Z-ratio of 0.6, the material demands high-power e-beam capability and careful rate control to avoid thermal damage to the source.
