This material requires thermal or resistive evaporation using a molybdenum, tungsten, or tantalum boat or a graphite or alumina crucible. The evaporation source hardware and process parameters must be matched to the material's melting point, Z-ratio, and granular form for consistent thin-film deposition.
- Evaporation Source Compatibility: The material can only be used with a molybdenum, tungsten, or tantalum boat or a graphite or alumina crucible for thermal resistive evaporation.
- Process Parameter Constraints: The evaporation process must be controlled based on the material's melting point of 420 °C and Z-ratio of 0.514 to achieve desired film properties.
- Granule Size Loading: The 3-6 mm granules must be loaded into the evaporation source to ensure even distribution and prevent bridging during heating.
- Deposition Method Preference: Thermal or resistive evaporation is the preferred method, with low-power e-beam evaporation allowed only as an optional alternative.
Why is thermal/resistive evaporation preferred over e-beam for zinc granules?
Thermal/resistive evaporation is preferred for zinc granules because zinc has a low melting point of 420°C, making it well-suited for thermal evaporation. Low-power e-beam is optional but may require careful power control to avoid overheating or splashing the material. The product specification lists the melting point at 420°C and density at 7.14 g/cm³, supporting this recommendation.
What crucible or boat materials are compatible with evaporating zinc granules?
Zinc evaporation material is compatible with Mo/W/Ta boats or graphite/alumina crucibles, as specified in the product technical specifications. These materials can withstand the zinc melting point of 420°C and provide a clean evaporation source. The product is supplied as granules of 3-6 mm size to fit these sources.
What is the significance of the Z-ratio of 0.514 for zinc evaporation material?
The Z-ratio of 0.514 is a material-specific constant used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance of zinc. Accurate Z-ratio values are essential for precise thin-film thickness control during vacuum deposition. The product lists this value explicitly to support process calibration.
Zinc (Zn) evaporation material supplied as 99.99% pure granules (3-6 mm) for thermal/resistive evaporation. The 420°C melting point and 0.514 Z-ratio dictate specific boat/crucible selection and process tuning, while pack size options (100g–1kg) support batch scaling.
Positive
- High purity specification: 99.99% purity minimizes contamination in deposited films, enabling consistent optical and electrical properties for thin-film applications.
- Controlled granule size range: Granules sized 3-6 mm facilitate uniform source loading and predictable evaporation rates in thermal or low-power e-beam systems.
Trade-offs
- Specific hardware requirements: Optimal evaporation requires Mo/W/Ta boats or graphite/alumina crucibles; users without compatible source hardware must adapt their deposition setup.
- Process parameter sensitivity: Melting point of 420°C and Z-ratio of 0.514 demand careful power calibration and rate monitoring, particularly in e-beam systems where low-power operation is recommended.
