Barium titanate evaporation powder requires use of an e-beam hearth with specific liner materials or refractory metal boats for thermal evaporation. The material's melting point and Z-ratio must be accounted for in deposition source selection and process parameter matching.
- Evaporation Source Hardware: Use an e-beam hearth with a graphite, Al2O3, or BN liner, or a W, Mo, or Ta boat for thermal evaporation by RFQ.
- Process Parameter Matching: Match the evaporation source hardware and process route to the material's melting point (1,625°C), density (6.02 g/cm³), and Z-ratio (0.464) for optimal film deposition.
- Pre-Order Compatibility Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before placing a quotation request.
Why is e-beam evaporation preferred over thermal evaporation for BaTiO3 powder?
E-beam evaporation is preferred for BaTiO3 powder due to the material's high melting point (1,625°C) and the need for controlled, localized heating to avoid decomposition. Thermal evaporation is available by RFQ but requires specific liner materials (graphite, Al2O3, BN) or refractory metal boats (W/Mo/Ta) to handle the temperature and chemical reactivity.
What are the recommended liner materials for e-beam evaporation of BaTiO3?
For e-beam evaporation, BaTiO3 powder should be loaded into a hearth lined with graphite, Al2O3, or BN to prevent contamination and ensure thermal stability. Alternatively, W/Mo/Ta boats can be used for thermal evaporation, but this requires a formal RFQ process.
What is the significance of the Z-ratio value listed for BaTiO3 evaporation material?
The Z-ratio of 0.464 is a material-specific parameter used in quartz crystal microbalance (QCM) or other deposition rate monitors to correct for acoustic impedance differences between the crystal and the deposited film. This value must be programmed into the deposition controller to ensure accurate thickness and rate measurements during BaTiO3 thin-film deposition.
Barium Titanate (BaTiO3) evaporation material in powder form with 99.95% purity and 90 nm particle size, specified for e-beam evaporation with defined melting point (1625°C), density (6.02 g/cm³), and Z-ratio (0.464) to support thin-film deposition process matching.
Positive
- High purity and controlled particle size: 99.95% purity with 90 nm powder ensures consistent evaporation behavior and film stoichiometry in high-vacuum deposition.
- Well-characterized thermophysical properties: Specified melting point (1,625°C), density (6.02 g/cm³), and Z-ratio (0.464) enable direct calculation of deposition parameters for e-beam or thermal evaporation systems.
Trade-offs
- E-beam preferred; thermal requires RFQ: Evaporation is optimized for e-beam hearth; thermal evaporation requires RFQ with specific liner (graphite/Al2O3/BN) or boat (W/Mo/Ta) hardware, adding procurement lead time.
- Powder form requires careful handling: As a 90 nm powder, the material is prone to airborne dispersion and moisture adsorption, necessitating glovebox handling and sealed storage to maintain purity and prevent source contamination.
