Calcium evaporation material requires inert atmosphere handling to prevent oxidation and moisture reaction. Compatibility with Ta/Mo/W boats or crucibles is necessary for thermal or e-beam evaporation processes.
- Inert Atmosphere Handling: Handle the material under inert atmosphere to avoid degradation from air exposure.
- Boat and Crucible Compatibility: Use only with tantalum, molybdenum, or tungsten boats or crucibles for evaporation.
- Evaporation Method Constraints: Thermal/resistive evaporation or low-power e-beam may be used upon RFQ confirmation.
- Source Loading Constraints: Pieces of 1-10 mm size are suitable for loading into the evaporation source.
- Process Matching Requirement: Deposition source geometry and process route must be matched to the material's melting point and film requirements.
What is the significance of the Z-ratio of 2.62 for Calcium (Ca) evaporation material in thin-film deposition?
The Z-ratio of 2.62 is a calibration parameter for quartz crystal microbalance (QCM) thickness monitors used in thermal evaporation. It must be entered into the deposition controller to accurately measure the deposition rate and film thickness of calcium, as the material density (1.54 g/cm³) and acoustic impedance affect the crystal response.
Which crucible or boat materials are recommended for evaporating Calcium (Ca) pieces?
The recommended evaporation source materials are tantalum (Ta), molybdenum (Mo), or tungsten (W) boats or crucibles, paired with an inert handling package. These refractory metals withstand the 839°C melting point of calcium during thermal or low-power e-beam evaporation.
What handling and storage conditions are required for Calcium (Ca) evaporation material pieces?
Calcium is a reactive metal, so the product is supplied with an inert handling package to prevent oxidation or moisture absorption. Store under inert atmosphere (e.g., argon or nitrogen) and handle in a glovebox or dry environment to maintain the 99.9% purity specification before deposition.
Calcium (Ca) evaporation material in pieces (1–10 mm) at 99.9% purity is suitable for thermal/resistive evaporation and low-power e-beam deposition. The defined piece size aids uniform source loading, but the reactive nature of calcium mandates inert handling and careful process control to avoid oxidation and evaporation instability.
Positive
- Specified 99.9% purity grade: Reduces contamination risk in thin-film deposition, enabling consistent film stoichiometry and electrical properties for research-grade applications.
- Controlled piece size 1–10 mm: Facilitates predictable loading and uniform evaporation from Ta/Mo/W boats or crucibles, minimizing source bridging and process variability.
Trade-offs
- Requires inert handling and storage: Calcium is highly reactive with atmospheric oxygen and moisture, necessitating inert atmosphere packaging and glovebox handling to prevent oxidation that degrades film purity.
- Process sensitivity due to low density: Density of 1.54 g/cm³ and melting point at 839°C demand careful evaporation source design and temperature ramping to avoid spitting or uneven flux during deposition.
