This evaporation material requires moisture-controlled handling during storage and deposition to prevent hydration and ensure consistent film quality. Compatibility with specific evaporation source materials and process methods must be confirmed before use to avoid source damage or contamination.
- Moisture Sensitivity: Store and handle under dry conditions to avoid moisture absorption which can alter evaporation behavior.
- Source Material Compatibility: Use W/Mo/Ta boats or graphite/alumina crucibles as recommended to prevent chemical reaction with molten KBr.
- Preferred Evaporation Method: Employ thermal or resistive evaporation as the primary method; electron-beam evaporation requires special quotation and evaluation.
- Process Matching: Match the deposition source hardware and process parameters to the material's melting point of 734°C and density of 2.75 g/cm³.
- Handling Precautions: Avoid exposure to humidity and contaminants during loading to maintain material purity and film integrity.
Why is thermal/resistive evaporation preferred over e-beam for Potassium Bromide (KBr) evaporation material?
Thermal/resistive evaporation is the preferred method for KBr evaporation material due to its lower melting point (734°C) and compatibility with standard boat or crucible materials. The product specification lists thermal/resistive evaporation as the preferred method, with e-beam available only by RFQ, and recommends using W/Mo/Ta boats or graphite/alumina crucibles. This ensures controlled deposition without excessive thermal stress on the material.
Which boat or crucible materials are compatible with KBr evaporation material?
Compatible evaporation source hardware includes W (tungsten), Mo (molybdenum), or Ta (tantalum) boats, as well as graphite or alumina crucibles, as explicitly stated in the product specification. Buyers should confirm their deposition source geometry and match the selected boat or crucible material to the KBr pieces (1–3 mm size) for optimal thermal transfer and evaporation uniformity.
What handling and storage conditions are required for Potassium Bromide (KBr) evaporation material?
The product requires moisture-controlled handling, indicating that KBr is sensitive to humidity and should be stored in a dry environment to maintain its 99.9% purity and piece integrity. Buyers should review the safety data sheet and confirm shipment conditions before quotation, as the material is supplied in pack sizes from 25 g to 1 kg and must be protected from moisture during storage and handling.
This evaluation covers Potassium Bromide (KBr) evaporation material at 99.9% purity in 1-3 mm pieces, suitable for thermal/resistive deposition with W/Mo/Ta boats or graphite/alumina crucibles, with moisture-controlled handling required.
Positive
- 99.9% purity with 1-3 mm pieces: The material is supplied at 99.9% purity as 1-3 mm pieces, enabling precise matching to deposition process requirements and source loading constraints.
- Broad evaporation source compatibility: Compatible with W/Mo/Ta boats or graphite/alumina crucibles, with thermal/resistive evaporation preferred and e-beam available by RFQ, offering flexibility in deposition hardware selection.
Trade-offs
- Moisture-sensitive handling required: KBr is hygroscopic; moisture-controlled handling and storage are necessary to prevent degradation and ensure consistent evaporation behavior.
- E-beam evaporation by RFQ only: While thermal/resistive evaporation is preferred, e-beam evaporation is available only by request for quotation, which may require additional lead time and specification.
