Only use E-beam evaporation with graphite, Al2O3, or BN liner or a W/Mo/Ta boat for optimal performance. Confirm source geometry and pack size before ordering to ensure compatibility with deposition hardware.
- Evaporation Method Preference: E-beam evaporation is preferred; thermal evaporation requires a request for quotation to validate compatibility.
- Particle Size Handling: The powder form with particle size under 180 nm requires careful handling to avoid airborne contamination and ensure consistent deposition rates.
- Melting Point and Power Requirement: The material's high melting point of 2307 °C necessitates adequate power and hearth design for complete evaporation.
- Z-Ratio Calibration: A Z-ratio of 1.00 indicates minimal thickness monitor calibration adjustment, but verify with actual tooling factor during process setup.
How does the <180 nm particle size of Lanthanum Oxide powder affect its suitability for e-beam vs. thermal evaporation?
The <180 nm particle size ensures a fine, consistent powder for uniform source loading and reduced spitting during evaporation. E-beam evaporation is preferred with good performance using a graphite, Al2O3, or BN liner, while thermal evaporation is available by RFQ. The fine particle size supports reliable deposition in both methods, but e-beam is recommended for optimal results.
What liner and boat materials are recommended for evaporating 99.995% Lanthanum Oxide (La2O3) powder?
For e-beam evaporation, use a graphite, Al2O3, or BN liner. For thermal evaporation, use a W, Mo, or Ta boat. These recommendations are based on the material's melting point of 2,307°C and density of 6.51 g/cm³, as specified in the product documentation. The Z-ratio of 1.00 also indicates compatibility with standard quartz crystal microbalance monitoring.
What physical properties of Lanthanum Oxide (La2O3) evaporation material are critical for deposition process control?
The critical physical properties are a melting point of 2,307°C, density of 6.51 g/cm³, and Z-ratio of 1.00. These values determine the required evaporation power, deposition rate calibration, and film thickness monitoring accuracy. The 99.995% purity and <180 nm particle size further ensure minimal contamination and consistent evaporation behavior.
Lanthanum Oxide (La2O3) evaporation material in powder form with 99.995% purity and <180 nm particle size is evaluated for vacuum thin-film deposition. The material offers high purity and compatibility with e-beam evaporation, but requires careful source hardware matching and a non-standard thermal evaporation process.
Positive
- High purity and controlled particle size: 99.995% purity and <180 nm particle size ensure consistent film stoichiometry and reduced particulate contamination in vacuum thin-film deposition.
- Versatile evaporation source compatibility: Compatible with e-beam evaporation (preferred) and thermal evaporation by RFQ, supporting various liner and boat materials including graphite, Al2O3, BN, W, Mo, and Ta.
Trade-offs
- Non-standard thermal evaporation process: Thermal evaporation requires RFQ and is not a standard configuration; buyers must confirm process compatibility and hardware setup before ordering.
- Evaporation source hardware matching required: Evaporation source hardware and process route must be matched to the material's melting point (2307°C) and film requirements, as stated in the application matching guidelines.
