Strontium metal pieces are air- and moisture-sensitive and require storage under an inert atmosphere to prevent oxidation and degradation. All handling must be performed in a glovebox or under inert gas flow to maintain material integrity for vacuum deposition.
- Inert Atmosphere Storage: Store the sealed inert package in a dry, oxygen-free environment at ambient temperature.
- Moisture Sensitivity: Exposure to atmospheric moisture can cause surface oxidation and compromise film purity.
- Handling Procedure: Open the inert package only inside a glovebox filled with argon or nitrogen.
- Crucible Compatibility: Use only tantalum, molybdenum, or tungsten boats or crucibles to avoid contamination of the evaporation source.
- Evaporation Method: Thermal resistive evaporation or low-power e-beam evaporation are recommended; confirm source geometry with technical sales.
This procedure outlines the steps to load strontium evaporation material into a deposition system while preventing oxidation and achieving consistent film deposition. All steps require inert atmosphere conditions until the chamber is evacuated.
Required Equipment: Glovebox, Argon gas supply, Tantalum boat or crucible, Vacuum deposition chamber
- Transfer Material
Transfer the required quantity of strontium pieces from the inert package to the crucible inside an argon-filled glovebox. - Load Crucible
Load the filled crucible into the evaporation source assembly while maintaining argon flow over the material. - Evacuate Chamber
Close the deposition chamber and evacuate to the base pressure required for your process. - Outgas Material
Apply a low pre-heat current to outgas any surface contaminants before ramping to evaporation temperature. - Evaporate
Ramp the source power to achieve the desired deposition rate while monitoring film thickness.
What is the significance of the Z-Ratio of 1.00 for this strontium evaporation material in quartz crystal microbalance monitoring?
The Z-Ratio of 1.00 for this Strontium evaporation material indicates an acoustic impedance match to the quartz crystal sensor, simplifying thickness monitoring calibration. This value is provided as a reference; users should verify with their deposition system's tooling factor. The product's density of 2.6 g/cm³ and melting point of 769°C are additional parameters for process control.
Why is a tantalum, molybdenum, or tungsten boat or crucible specified for evaporating strontium pieces?
Strontium is a reactive alkaline earth metal that can alloy with or react with certain crucible materials at its melting point of 769°C. Tantalum, molybdenum, and tungsten are refractory metals with high melting points and low reactivity with strontium, making them suitable for thermal or low-power e-beam evaporation. An inert handling package is also recommended to minimize oxidation during storage and loading.
What special handling and storage conditions are required for strontium evaporation pieces?
The product is supplied with an inert handling package to minimize exposure to air and moisture. For detailed handling precautions and storage recommendations, users should review the safety data sheet. Strontium is a reactive metal; proper storage in a dry, inert atmosphere is advisable to maintain material integrity.
Strontium (Sr) evaporation pieces at 99.99% purity and 1–10 mm size are suitable for thermal/resistive or low-power e-beam deposition using Ta/Mo/W boats or crucibles, with inert handling required due to the material's reactivity and oxidation sensitivity.
Positive
- High purity 99.99%: The 99.99% purity specification minimizes contamination in deposited thin films, critical for reproducible electronic or optical properties in research applications.
- Multiple pack size options: Available in 100g, 500g, and 1kg packs allows researchers to scale procurement to experimental needs without excess material waste.
Trade-offs
- Inert handling required: Strontium is reactive and requires inert atmosphere handling and packaging to prevent oxidation before deposition, adding to laboratory infrastructure needs.
- Source compatibility verification: Buyers must confirm that their deposition system's boat or crucible material (Ta, Mo, W) is compatible with strontium's melting point and reactivity to avoid contamination or equipment damage.
