This material requires specific evaporation source hardware and process conditions. Compatibility with crucible materials and deposition method must be confirmed before use.
- Evaporation Method: Thermal evaporation or low-power e-beam is recommended for this material; confirm specific parameters via RFQ.
- Crucible Compatibility: Use quartz, alumina, graphite crucible, tantalum or tungsten boat, or Knudsen cell; verify material compatibility with BaS.
- Melting Point Consideration: Melting point at 1200°C requires deposition system capable of reaching and maintaining that temperature.
- Physical Form Handling: Pieces of 1-3 mm must be loaded carefully into the evaporation source to ensure uniform deposition and avoid particle loss.
- Documentation Verification: Confirm certificate of analysis, safety data sheet, and shipment conditions prior to use.
What is the melting point of BaS evaporation material and what deposition methods are recommended?
The melting point of Barium Sulfide (BaS) is listed as approximately 1200 in the specifications. This material is recommended for thermal evaporation or low-power e-beam deposition by RFQ using compatible sources such as quartz/alumina/graphite crucibles or Ta/W boats.
What crucible or boat materials are compatible with BaS evaporation?
Compatible evaporation source hardware includes quartz/alumina/graphite crucibles and Ta/W boats for thermal evaporation or low-power e-beam processes. Molybdenum (Mo) is also listed as an option in the hardware table; for custom configurations such as Knudsen cells an RFQ is required.
How does the piece size (1–3 mm) affect loading into evaporation sources?
The pieces are sized between 1–3 mm to facilitate controlled loading into crucibles or boats for thermal evaporation or e-beam sources. This size range supports uniform filling of the source cavity and consistent evaporation rates during vacuum thin-film deposition.
Barium Sulfide (BaS) evaporation material in 1-3 mm pieces at 99.99% purity offers a defined composition and particle size for thermal or low-power e-beam deposition, with a melting point of 1,200°C requiring compatible crucible materials such as quartz, alumina, or graphite.
Positive
- High purity (99.99%) for film quality: The 99.99% purity specification minimizes trace element contamination in deposited thin films, supporting reproducible optical or electronic properties in research applications.
- Defined particle size (1-3 mm): The pieces are sized 1-3 mm to enable consistent loading into evaporation sources and controlled sublimation behavior during thermal or e-beam deposition.
Trade-offs
- High melting point requires specialized hardware: With a melting point of 1,200°C, this material necessitates high-temperature evaporation sources such as e-beam or thermal boats with refractory metal or ceramic crucibles, increasing infrastructure demands.
- Crucible compatibility must be verified: The evaporation source options include quartz, alumina, graphite, Ta/W boat, or Knudsen cell; improper crucible selection may lead to chemical reaction or contamination at elevated temperatures.
