This material is a research-grade compound evaporation powder for vacuum thin-film deposition. Its processing constraints include specific deposition source compatibility and preferred evaporation method.
- Deposition Source Compatibility: E-beam hearth with graphite/Al2O3/BN liner or W/Mo/Ta boat is required for optimal evaporation performance.
- Evaporation Method Preference: E-beam evaporation is the preferred method; thermal evaporation is available only by RFQ.
- Process Parameter Matching: Melting point (2852°C), density (3.58 g/cm³), and Z-ratio (0.411) must be matched to hardware and film requirements.
What is the significance of the 99.5% purity and 45 nm particle size for MgO evaporation material?
The 99.5% purity ensures standard-grade MgO films, while the 45 nm powder size promotes uniform evaporation and consistent film stoichiometry. The source indicates E-beam performance is Good with this material, but RFQ may be required for thermal evaporation. The melting point of 2,852°C and density of 3.58 g/cm³ also influence deposition rate and film density.
Which crucible liners or boats are recommended for evaporating MgO powder in an e-beam system?
The source specifies that MgO powder is compatible with e-beam hearths using graphite, Al2O3, or BN liners, or with W, Mo, or Ta boats. The sheet2 hardware option is graphite. Selecting the correct liner is critical to avoid contamination and ensure efficient heat transfer.
What are the melting point, density, and Z-ratio of MgO, and how do they affect deposition system setup?
The melting point is 2,852°C, density is 3.58 g/cm³, and Z-ratio is 0.411. These parameters determine the required e-beam power, crucible material, and quartz crystal monitor calibration for accurate thickness control.
This MgO evaporation material (99.5% purity, 45 nm powder) is optimized for E-beam evaporation with graphite/Al2O3/BN liners or W/Mo/Ta boats, offering good performance for thin-film deposition of MgO.
Positive
- High purity and controlled particle size: 99.5% purity and 45 nm powder size enable consistent deposition rates and film stoichiometry for applications requiring precise MgO layers.
- Good E-beam evaporation performance: Rated 'Good' for E-beam evaporation with compatible hearth liners (graphite, Al2O3, BN) or W/Mo/Ta boats, ensuring reliable source coupling and film quality.
Trade-offs
- Specific source hardware required: Optimal performance demands graphite, Al2O3, or BN liners for E-beam hearths, or W/Mo/Ta boats, limiting compatibility with standard unlined crucibles or other boat materials.
- Thermal evaporation only by RFQ: Thermal evaporation is not directly supported; buyers must request a quotation for this route, adding lead time and requiring custom process validation.
