Zinc evaporation material requires thermal or resistive evaporation using Mo/W/Ta boats or graphite/alumina crucibles. The material's melting point of 420°C and Z-ratio of 0.514 must be matched to the deposition process for controlled film growth.
- Evaporation Source Compatibility: Use only Mo/W/Ta boats or graphite/alumina crucibles to avoid contamination and ensure proper wetting.
- Evaporation Method: Thermal or resistive evaporation is preferred, while low-power e-beam is optional and requires careful parameter adjustment.
- Melting Point Consideration: The 420°C melting point requires precise temperature control to prevent premature evaporation or spitting.
- Z-Ratio for Rate Monitoring: The Z-ratio of 0.514 must be entered into the deposition controller for accurate thickness monitoring.
- Granule Size Handling: Granules of 1-3 mm size require uniform loading in the source to avoid bridging and ensure consistent evaporation.
How does the Z-ratio of 0.514 for Zinc evaporation material affect film thickness monitoring during deposition?
The Z-ratio of 0.514 is used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness monitoring. A lower Z-ratio indicates a higher frequency shift per mass deposited, requiring correction factors. The specified value of 0.514 is explicitly listed for this 99.999% pure Zinc granular material, ensuring proper process control in thermal or e-beam evaporation.
What boat or crucible materials are compatible with 99.999% pure Zinc granules for thermal evaporation?
The Zinc granules are compatible with Mo/W/Ta boats or graphite/alumina crucibles for thermal resistive evaporation. Low-power e-beam evaporation is also optional. The product description explicitly states 'Evaporation Source: Mo/W/Ta boat or graphite/alumina crucible' and 'Evaporation Method: Thermal/resistive evaporation preferred; low-power e-beam optional.'
What documentation and safety considerations should be reviewed before procuring Atomfair 99.999% Zinc evaporation granules?
Buyers should confirm the certificate of analysis, safety data sheet (SDS), shipment conditions, and export requirements. The product page advises reviewing 'Certificate, safety data sheet, shipment condition and export requirements' against laboratory use. Additionally, the material is supplied as 99.999% pure Zinc granules in 1-3 mm size, with available pack sizes of 25g, 100g, 500g, and 1kg, and deposition-source compatibility must be verified before quotation.
This Zinc evaporation material (99.999% purity, 1–3 mm granules) is optimized for thermal/resistive evaporation with low-power e-beam option, delivering high-purity films for sensitive thin-film applications. Key constraints include source hardware compatibility (Mo/W/Ta boat or graphite/alumina crucible) and process tuning required due to its low melting point (420°C) and Z-ratio (0.514).
Positive
- High purity (99.999%): The 99.999% purity specification minimizes contamination in deposited thin films, making it suitable for research-grade vacuum deposition requiring precise stoichiometry and low defect densities.
- Optimized granule size for thermal evaporation: Granules sized 1–3 mm are compatible with Mo/W/Ta boats and graphite/alumina crucibles, enabling controlled feed in thermal/resistive evaporation and low-power e-beam systems.
Trade-offs
- Deposition source hardware dependency: Evaporation requires specific source hardware (Mo/W/Ta boat or graphite/alumina crucible); buyers must verify compatibility with their existing deposition system before ordering.
- Process sensitivity due to low melting point: With a melting point of 420°C and Z-ratio of 0.514, evaporation rate control is critical to avoid splashing or non-uniform film growth, necessitating careful process tuning.
