This magnesium oxide evaporation material must be used with compatible deposition source hardware and the preferred e-beam evaporation method. The material's high melting point and Z-ratio require specific calibration and process matching.
- Evaporation Source Compatibility: E-beam evaporation with graphite, alumina, or boron nitride liners, or tungsten, molybdenum, or tantalum boats is required for this material.
- Process Route Selection: E-beam evaporation is the preferred method; thermal evaporation requires quotation and may yield different performance characteristics.
- Melting Point Consideration: With a melting point of 2,852°C, the evaporation source must be capable of sustaining high temperatures for consistent deposition.
- Thickness Calibration: The Z-ratio of 0.411 must be applied to the thickness monitor for accurate film thickness measurement.
What evaporation source liner materials are compatible with this MgO powder for optimal e-beam evaporation performance?
For optimal e-beam evaporation performance, this MgO powder is recommended for use with a graphite, Al2O3, or BN liner, or a W/Mo/Ta boat. The specified sheet2 hardware is graphite (C,Al2O3). These liners provide the necessary thermal and chemical compatibility for the 2,852°C melting point material.
Can this MgO powder be used for thermal evaporation, or is e-beam evaporation the only option?
E-beam evaporation is the preferred method for this MgO powder, rated as good. Thermal evaporation is available only by request for quotation (RFQ). Buyers should confirm their deposition source geometry and process route before ordering.
What is the Z-ratio of this MgO powder and why is it important for deposition monitoring?
The Z-ratio of this MgO powder is 0.411. This value is critical for accurate quartz crystal microbalance (QCM) sensor calibration during thin-film deposition, ensuring correct film thickness monitoring.
This MgO powder (99.95%, <90 nm) is suitable for e-beam evaporation with graphite/Al2O3/BN liners, offering high purity for thin-film deposition but requiring careful source matching due to its high melting point and specific liner requirements.
Positive
- High purity (99.95%): The 99.95% purity specification enables consistent film stoichiometry and reduces contamination risk in sensitive optical or electronic thin-film applications.
- Sub-90 nm particle size: The <90 nm powder form supports uniform source loading and stable evaporation rates, particularly in e-beam systems where fine particle size improves thermal contact and vaporization consistency.
Trade-offs
- High melting point requires high-energy e-beam: With a melting point of 2,852 °C, the material demands high-power e-beam sources; thermal evaporation is only available by RFQ, limiting process flexibility.
- Specific liner compatibility required: Optimal evaporation performance requires graphite, Al2O3, or BN liners (or W/Mo/Ta boats), which may not be standard lab inventory and must be procured separately.
