Calcium evaporation material requires inert atmosphere handling to prevent oxidation during storage and loading. Deposition source hardware must be compatible with the material's melting point of 839°C and specified boat or crucible material (Ta, Mo, or W).
- Inert Atmosphere Handling: Handle and store the calcium pieces under inert atmosphere to prevent oxidation and moisture contamination.
- Deposition Source Material: Use only tantalum, molybdenum, or tungsten boats or crucibles for thermal evaporation of calcium.
- Piece Size Selection: Select pieces within the 1-10 mm size range to ensure proper loading and consistent evaporation.
- Process Temperature: Achieve a process temperature of at least 839°C to melt and evaporate the calcium efficiently.
What is the significance of the Z-ratio of 2.62 for calcium evaporation in e-beam deposition?
The Z-ratio of 2.62 is a calibration factor required for quartz crystal microbalance (QCM) thickness monitoring during e-beam deposition. It compensates for the acoustic impedance mismatch between the quartz crystal and the deposited calcium film. Entering this value into the deposition controller is essential to obtain accurate film thickness readings; using default values can lead to significant errors.
Why are tantalum, molybdenum, or tungsten boats required for evaporating calcium?
Calcium is chemically reactive at evaporation temperatures. Tantalum, molybdenum, and tungsten are recommended for the boat or crucible because of their high melting points and compatibility with molten calcium. The product description explicitly specifies Ta/Mo/W as the required source materials to avoid contamination or reaction with the crucible.
What inert handling precautions are needed for calcium evaporation material?
The calcium pieces (1–10 mm, 99.99% purity) are supplied with an inert handling package to minimize exposure to ambient moisture and oxygen. Laboratories should open the package only in an inert-atmosphere glovebox or immediately before loading into a vacuum system. Storage in a dry, inert environment is required to preserve the specified purity and prevent surface oxidation that could affect deposition uniformity.
This calcium evaporation material (99.99% purity, 1–10 mm pieces) is suited for research-grade thin-film deposition, requiring inert handling and process-matched source hardware to achieve reliable results.
Positive
- High purity 99.99%: The 99.99% purity specification enables consistent thin-film properties and reduces contamination risk in vacuum deposition processes.
- Controlled piece size 1–10 mm: The defined 1–10 mm piece size range facilitates uniform source loading and predictable evaporation behavior in thermal or e-beam sources.
Trade-offs
- Inert handling required: Calcium is supplied with an inert handling package to prevent oxidation during storage and loading; standard laboratory air exposure may compromise material quality.
- Process matching needed: The evaporation source hardware (Ta/Mo/W boat or crucible), process route (thermal or e-beam), and parameters must be matched to calcium's melting point (839°C), density (1.54 g/cm³), and Z-ratio (2.62) to achieve reliable film deposition.
