EHS review is mandatory before using this material in E-beam or thermal evaporation processes. Dedicated crucible or liner must be specified via RFQ to ensure compatibility with the deposition source geometry.
- EHS Review Requirement: EHS review must be completed prior to any evaporation run to confirm safe handling and containment.
- Crucible/Liner Compatibility: Dedicated crucible or liner must be selected via RFQ to match the source hardware and avoid cross-contamination.
- Purity Verification: The 99.999% purity specification must be verified against the deposition requirements to ensure film quality.
- Melting Point Constraint: Evaporation temperature must be set relative to the melting point of 321°C to prevent material splattering or incomplete vaporization.
- Z-Ratio Calibration: The Z-ratio of 0.682 must be entered into the deposition controller for accurate film thickness monitoring.
What is the Z-ratio of the 99.999% cadmium pellets and why is it specified for e-beam evaporation?
The Z-ratio is 0.682. This parameter is used in quartz crystal microbalance (QCM) monitoring to correct for acoustic impedance mismatch, ensuring accurate film thickness measurement during e-beam deposition. The value is provided to allow users to configure their deposition controllers appropriately.
What crucible or liner is required for evaporating cadmium pellets, and what evaporation methods are allowed?
A dedicated crucible or liner must be specified via RFQ to avoid cross-contamination. The material can be used with e-beam or thermal evaporation, but only after an Environmental Health and Safety (EHS) review. This is due to the specific handling requirements of cadmium.
What are the available pack sizes for the cadmium pellets and what is the minimum order quantity?
The minimum order quantity is 25g, and available pack sizes include 25g, 100g, 500g, and 1kg. Indicative price tiers are provided, with 25g at USD 200, 100g at USD 420, 500g at USD 1050, and 1kg at USD 1400. Buyers should confirm the required quantity and pack size before quotation.
Atomfair's Cadmium evaporation material pellets (99.999%, 1-3 mm) offer high purity for sensitive thin-film deposition, but require dedicated EHS review and crucible hardware due to cadmium's toxicity and low melting point (321°C).
Positive
- High purity for sensitive films: 99.999% purity minimizes contamination in thin-film deposition, suitable for optoelectronic or semiconductor applications where trace impurities affect device performance.
- Specified pellet size for loading: Pellets of 1-3 mm dimension facilitate consistent loading into evaporation sources and controlled evaporation rates.
Trade-offs
- EHS review required for use: Cadmium's toxicity mandates an environmental health and safety review before thermal or e-beam evaporation, adding procedural steps and requiring dedicated crucible liners.
- Low melting point limits options: Melting point of 321°C restricts evaporation to methods that can precisely control low-temperature deposition, and may require specialized source hardware.
