Chromium oxide evaporation material requires deposition source compatibility with e-beam hearth liners or thermal boats. Process parameters must be matched to its melting point, density, and Z-ratio for consistent film deposition.
- Deposition Source Requirement: Use an e-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat for thermal evaporation.
- Evaporation Method Preference: E-beam evaporation is the preferred method; thermal evaporation requires prior quotation and approval.
- Material Melting Point: A melting point of 2266°C requires adequate source power and thermal management to achieve complete evaporation.
- Density and Z-Ratio Calibration: The density of 5.21 g/cm³ and Z-ratio of 1.00 simplify quartz crystal microbalance calibration for film thickness monitoring.
Why is the Z-ratio of this Cr2O3 evaporation material listed as 1.00, and how does it affect deposition rate monitoring?
The Z-ratio of 1.00 indicates that the acoustic impedance of Cr2O3 matches the quartz crystal, simplifying tooling factor calibration and improving thickness monitoring accuracy during e-beam evaporation. This value is explicitly stated in the product specifications for this 99.8% purity, 55 nm powder material.
What crucible or boat materials are recommended for evaporating Cr2O3 powder in an e-beam system?
The recommended evaporation source hardware includes an e-beam hearth with a graphite, Al2O3, or BN liner, or a W/Mo/Ta boat. These materials are compatible with the high melting point (2266°C) and chemical properties of Cr2O3, as specified in the product description.
How does the melting point of Cr2O3 (2266°C) influence the preferred evaporation method for this powder?
The high melting point of 2266°C makes e-beam evaporation the preferred method, as it can achieve the necessary temperatures. Thermal evaporation may be considered only by RFQ, as it is less suitable for such high-melting-point materials. This guidance is provided in the product specifications.
Chromium Oxide (Cr2O3) powder, 99.8% purity, 55 nm particle size, is optimized for e-beam evaporation using graphite/Al2O3/BN liners or W/Mo/Ta boats, with good performance. The variable pack sizes (25g–1kg) accommodate lab to small-scale production, but hardware compatibility and pre-order documentation verification are required.
Positive
- Defined purity and particle size: 99.8% purity and 55 nm particle size ensure consistent evaporation behavior and film quality for vacuum deposition.
- Good e-beam performance with compatible liners: Rated 'Good' for e-beam evaporation when used with graphite/Al2O3/BN liners or W/Mo/Ta boats, providing reliable source loading and film uniformity.
Trade-offs
- Deposition hardware compatibility required: E-beam evaporation is preferred; thermal evaporation requires RFQ. Users must match source geometry and liner/boat materials to the specified hardware list.
- Pre-order verification necessary: Buyers must confirm model, purity, form, size range, pack size, and deposition-source compatibility before ordering, and review certificates and safety data sheets for lab compliance.
