What is the recommended evaporation method for CaO powder and why is E-beam preferred over thermal evaporation?
E-beam evaporation is preferred for CaO because its melting point of 2,614°C exceeds the typical operating range of thermal boats. The product specifies E-beam evaporation as preferred, using a hearth with graphite, Al2O3, or BN liner. Thermal evaporation is possible only by RFQ, requiring W/Mo/Ta boats, due to the high melting point and material reactivity.
What liner or boat materials are compatible with CaO evaporation given its high melting point?
For E-beam evaporation, compatible liners include graphite, Al2O3, and BN, which withstand the 2,614°C melting point and minimize chemical interaction. For thermal evaporation, W, Mo, and Ta boats are listed as options. The density of ~3.3 g/cm³ influences material handling and source loading.
How does the 10-70 nm particle size of CaO powder affect thin-film deposition performance?
The 10-70 nm particle size ensures uniform loading and consistent evaporation, reducing splatter and improving film homogeneity. This fine powder form allows predictable thermal contact with the hearth or boat, which is critical given CaO's high melting point of 2,614°C and density of ~3.3 g/cm³, enabling reproducible deposition rates.
Calcium Oxide (CaO) evaporation material in powder form with 99.99% purity and 10-70 nm particle size, suitable for E-beam evaporation with specified liner materials, but requiring careful source matching due to high melting point and deposition constraints.
Positive
- High purity and defined particle size: 99.99% purity and 10-70 nm particle size ensure consistent evaporation behavior and film quality for research-grade thin-film deposition.
- Flexible pack size options: Available in 25g, 100g, 500g, and 1kg pack sizes, allowing researchers to scale material procurement according to experimental needs.
Trade-offs
- Specific evaporation source requirements: Requires E-beam hearth with graphite/Al2O3/BN liner or W/Mo/Ta boat; thermal evaporation only by RFQ, limiting compatibility with standard thermal evaporation systems.
- High melting point operational constraint: Melting point of 2,614°C necessitates high-temperature evaporation hardware and careful thermal management, increasing infrastructure demands.
