Calcium pellets are moisture- and oxygen-sensitive and require inert handling during storage and loading. Evaporation source hardware must be compatible with reactive metals, and the process route must be matched to the material's melting point and film requirements.
- Moisture Sensitivity: Calcium pellets must be stored and handled under inert atmosphere to prevent oxidation and degradation.
- Source Compatibility: Only Ta, Mo, or W boats or crucibles are suitable for evaporating calcium to avoid alloying or contamination.
- Process Route Matching: The evaporation method, whether thermal or low-power e-beam, must be selected based on the melting point and desired film properties.
How does the melting point of 839°C and density of 1.54 g/cm³ influence the evaporation rate and film quality for Calcium pellets?
The low melting point (839°C) and low density (1.54 g/cm³) of Calcium support thermal or low-power e-beam evaporation. However, the Z-ratio of 2.62 must be accounted for in quartz crystal microbalance thickness monitoring to achieve accurate film deposition. The pellet form (1–3 mm) ensures consistent source loading and controlled evaporation behavior.
What boat or crucible materials are recommended for evaporating Calcium pellets in thermal or e-beam processes?
Tantalum (Ta), molybdenum (Mo), or tungsten (W) boats or crucibles are recommended, paired with an inert handling package to prevent oxidation during loading. The product is specified for thermal/resistive evaporation or low-power e-beam by RFQ, and buyers should confirm deposition source geometry before quotation.
Why is an inert handling package required for Calcium evaporation material, and what storage conditions are recommended?
Calcium is highly reactive with oxygen and moisture, so an inert handling package is supplied to prevent oxidation and maintain 99.9% purity. The product description advises reviewing shipment conditions and safety data sheets, and recommends storage under inert atmosphere or vacuum to preserve material integrity before use.
Calcium (Ca) evaporation pellets (99.9% purity, 1-3 mm) for thermal or e-beam deposition. Requires inert handling and compatible boat materials (Ta, Mo, W). Melting point 839°C, density 1.54 g/cc, Z-ratio 2.62.
Positive
- Defined purity and pellet form: 99.9% purity and 1-3 mm pellet size ensure consistent source loading and predictable evaporation behavior in vacuum deposition processes.
- Broad evaporation method compatibility: Compatible with thermal/resistive and low-power e-beam evaporation using Ta, Mo, or W boats or crucibles, offering flexibility in system integration.
Trade-offs
- Requires inert handling and storage: Supplied with an inert handling package, indicating high reactivity with moisture and air; proper storage under inert atmosphere is mandatory to maintain material integrity.
- Low melting point and density constraints: Melting point of 839°C and density of 1.54 g/cc are low relative to many evaporation materials, which may influence heating rates, deposition uniformity, and require careful process parameter tuning.
