This material must be processed via E-beam evaporation using a graphite, Al2O3, or BN liner, or via thermal evaporation using a W, Mo, or Ta boat after RFQ. The 48 nm particle size and 99.75% purity require careful source loading and calibration against the melting point of 1,795 °C and Z-ratio of 0.412.
- Source Compatibility: The evaporation source must be an E-beam hearth with a graphite, Al2O3, or BN liner, or a W, Mo, or Ta boat for thermal evaporation.
- Particle Size Effect: The 48 nm powder size affects source loading density and evaporation uniformity, requiring verification of the deposition source geometry.
- Melting Point and Z-Ratio: The 1,795 °C melting point and 0.412 Z-ratio must be used to calibrate the deposition rate monitor and evaporation parameters.
- Purity Requirement: The 99.75% purity specification ensures minimal contamination in thin films, but requires confirmation of the certificate and batch consistency.
- Procurement Verification: Confirm the model, purity, form, particle size, pack size, and deposition-source compatibility before ordering to avoid process mismatches.
Why is the purity of Cobalt Oxide (CoO) evaporation material specified as 99.75% and what are the implications for thin-film deposition?
The 99.75% purity specification ensures minimal contamination for standard evaporative coating applications. The product description explicitly states that this purity level allows comparison between standard, high-purity, and RFQ-controlled grades, meaning buyers requiring stricter impurity limits can request a custom grade via RFQ.
What deposition hardware is compatible with this CoO powder evaporation material?
E-beam evaporation is the preferred method, using a hearth with a graphite, Al2O3, or BN liner. For thermal evaporation, an RFQ is required, and the compatible sources include W, Mo, or Ta boats. The product description provides these specific liner and boat options to guide hardware selection.
What is the Z-ratio of Cobalt Oxide (CoO) and why is it critical for deposition thickness monitoring?
The Z-ratio is 0.412. This value is used in quartz crystal microbalance (QCM) systems to correct for the acoustic impedance mismatch between the deposited material and the quartz crystal, ensuring accurate real-time film thickness measurement. The product specification lists this Z-ratio as a key parameter for deposition process control.
Cobalt Oxide (CoO) evaporation material supplied as 48 nm powder with 99.75% purity, designed for E-beam evaporation in vacuum thin-film deposition. Requires careful matching of deposition hardware and process parameters to its high melting point (1,795°C) and Z-Ratio (0.412).
Positive
- Defined material identity and purity: Cobalt Oxide (CoO) with 99.75% purity enables clear procurement matching and grade comparison for standard or high-purity deposition workflows.
- Specified powder form and particle size: Powder form with 48 nm particle size supports consistent source loading and evaporation behavior, facilitating reproducible thin-film deposition.
Trade-offs
- Requires pre-order compatibility confirmation: Deposition source geometry, pack size, certificate requirements, and shipment conditions must be confirmed before quotation to ensure operational fit.
- Process route must match material behavior: Evaporation source hardware and process parameters (e.g., E-beam vs. thermal) must be matched to CoO's melting point, density, and film requirements to avoid deposition issues.
