This product is a research-grade compound evaporation material for vacuum thin-film deposition. It requires careful matching of evaporation source hardware and process parameters to achieve optimal film quality.
- Evaporation Source Compatibility: Use an E-beam hearth with a graphite, Al2O3, or BN liner, or a W, Mo, or Ta boat for optimal performance.
- Evaporation Method Preference: E-beam evaporation is the preferred method; thermal evaporation may be possible by special quotation.
- Material Property Matching: The material's melting point (2307°C) and Z-ratio (1.00) must be considered when setting deposition parameters.
- Performance Note: E-beam evaporation performance is rated as Good with the specified source hardware.
What evaporation method is recommended for Atomfair Lanthanum Oxide (La2O3) powder with 99.995% purity?
E-beam evaporation is the preferred method for this Lanthanum Oxide powder, with performance rated as Good. Thermal evaporation is available by RFQ for specific applications. The material is designed for use in E-beam hearths with graphite, Al2O3, or BN liners, or with W/Mo/Ta boats.
Which liner or boat materials are compatible with E-beam evaporation of this Lanthanum Oxide powder?
Compatible liner materials for E-beam evaporation include graphite, aluminum oxide (Al2O3), and boron nitride (BN). Boat materials include tungsten (W), molybdenum (Mo), and tantalum (Ta). Additional sheet hardware options are graphite, tungsten, and tantalum as listed in the product specifications.
What does the Z-ratio value of 1.00 indicate for Lanthanum Oxide evaporation material?
The Z-ratio of 1.00 indicates that the acoustic impedance of Lanthanum Oxide matches the standard reference used in quartz crystal microbalance (QCM) monitoring. This simplifies film thickness calibration during deposition, as no correction factor is needed for the material's density of 6.51 g/cm³ and melting point of 2,307°C, both stated in the product specifications.
Lanthanum Oxide (La2O3) evaporation material in powder form with 99.995% purity and 8–190 nm particle size is suited for high-quality thin-film deposition via E-beam evaporation, offering consistent stoichiometry and controlled source loading. Operational constraints include the need for compatible hearth liners (graphite/Al2O3/BN) or refractory metal boats, and the high melting point (2,307°C) demands robust E-beam power delivery.
Positive
- High purity 99.995%: The 99.995% purity specification minimizes contamination in deposited films, enabling reproducible optical or dielectric properties in research-grade coatings.
- Controlled nanoscale particle size: The 8–190 nm powder size range facilitates uniform source loading and controlled evaporation rates, reducing spitting and improving film thickness uniformity.
Trade-offs
- High melting point requires robust E-beam: The melting point of 2,307°C demands high-power E-beam evaporation and compatible liner materials (graphite/Al2O3/BN or W/Mo/Ta boats); thermal evaporation is only available by RFQ, limiting process flexibility.
- Specific liner compatibility required: Optimal evaporation performance is achieved only with graphite/Al2O3/BN liners or W/Mo/Ta boats; incompatible hearth materials may cause contamination or poor deposition rates.
