This strontium evaporation material requires inert atmosphere handling to prevent oxidation and must be used with Ta/Mo/W boats or crucibles for thermal or e-beam deposition. Deposition source hardware and process parameters must be matched to the material's melting point and film requirements.
- Inert Atmosphere Handling: The material must be handled and stored under an inert atmosphere to maintain its specified purity and prevent reaction with ambient moisture or oxygen.
- Boat or Crucible Material Compatibility: Evaporation must be performed using tantalum, molybdenum, or tungsten boats or crucibles to avoid contamination or reaction with the molten strontium.
- Deposition Source Compatibility: The selected evaporation source hardware and process route must be compatible with the material's melting point (769°C) and intended film requirements.
- Pre-Order Verification: Deposition-source compatibility and material configuration must be confirmed with the supplier before placing an order to ensure proper process integration.
What is the significance of the 99.9% purity specification for strontium evaporation material and how does it affect thin film deposition?
The 99.9% purity specification provides a standard grade suitable for most thermal/resistive evaporation and low-power e-beam applications. The source explicitly notes that this purity level allows comparison between standard, high-purity, and RFQ-controlled grades, meaning higher-purity material can be sourced via RFQ if your application demands reduced contamination. The product also lists a melting point of 769 °C, density of 2.6 g/cm³, and a Z-ratio of 1.00, which are key parameters for deposition rate control and film uniformity.
What boat or crucible materials are compatible with strontium evaporation pellets during thermal deposition?
Strontium pellets are compatible with tantalum (Ta), molybdenum (Mo), or tungsten (W) boats or crucibles, as specified in the product description. An inert handling package is recommended to prevent oxidation of the reactive strontium during loading and deposition. The evaporation method can be thermal/resistive or low-power e-beam by RFQ, and the source geometry must be confirmed before ordering.
What special handling or storage conditions are required for strontium evaporation pellets to prevent degradation?
The product is supplied in an inert handling package to minimize oxidation and moisture exposure during storage and handling. Buyers must confirm shipment conditions and storage requirements with the supplier, as strontium is a reactive alkaline earth metal. The description emphasizes that an inert atmosphere is critical to maintain the 99.9% purity and pellet integrity before use.
Strontium pellets (99.9% purity, 1-3 mm) are suitable for thermal/e-beam evaporation using Ta/Mo/W crucibles, but require inert handling due to high reactivity. The low melting point (769°C) demands careful process control to maintain film quality.
Positive
- High purity (99.9%): The 99.9% purity specification enables consistent film stoichiometry and reduces contamination risk in vacuum deposition processes.
- Wide evaporation source compatibility: Compatible with Ta/Mo/W boats or crucibles and both thermal/resistive and low-power e-beam methods, providing flexibility for different deposition systems.
Trade-offs
- Requires inert handling: Strontium is reactive with air and moisture; an inert handling package is necessary to prevent oxidation or degradation during storage and loading.
- Low melting point (769°C): The relatively low melting point demands precise temperature control to avoid uncontrolled evaporation or splattering, affecting film uniformity.
