This silicon nitride evaporation powder requires e-beam evaporation with a compatible hearth liner and high-temperature crucible. The material's high melting point and nanoscale particle size impose specific processing conditions for thin-film deposition.
- Evaporation Source Compatibility: This material requires an e-beam hearth with a compatible liner; high-temperature crucible options are available by request for quotation.
- Evaporation Method Constraint: E-beam evaporation is the preferred method; thermal evaporation feasibility must be confirmed via request for quotation.
- High Melting Point: The material's melting point of 1900°C necessitates high-temperature crucible materials and appropriate substrate temperature control.
- Particle Size Specification: The 20-35 nm particle size range must be considered for source loading density and evaporation rate uniformity.
Why is e-beam evaporation preferred over thermal evaporation for Atomfair Silicon Nitride (Si3N4) powder?
E-beam evaporation is preferred because silicon nitride has a high melting point of 1,900°C, which makes thermal evaporation challenging. The product specification states that e-beam evaporation is the preferred method and that thermal feasibility requires a request for quotation (RFQ) to assess compatibility with high-temperature crucibles.
What is the significance of the 99.5% purity specification for this Si3N4 evaporation material?
The 99.5% purity specification indicates that the material contains at most 0.5% impurities, which is a standard research-grade level for evaporation materials. This allows comparison with higher-purity or RFQ-controlled grades, and for most thin-film deposition applications, this purity is sufficient to achieve reliable film properties.
What are the available pack sizes and indicative pricing tiers for the Atomfair Si3N4 powder?
The product is available in 25g, 100g, 500g, and 1kg pack sizes with indicative prices of USD 420, USD 950, USD 2500, and USD 3300 respectively. Bulk ordering at 1kg provides a cost per gram of USD 3.30 compared to USD 16.80 for 25g, offering significant savings for larger-scale research or production runs.
Silicon Nitride (Si3N4) evaporation material in powder form with 99.5% purity and 20-35 nm particle size is evaluated for E-beam evaporation deposition, requiring a compatible liner or high-temperature crucible due to its high melting point of 1,900°C and density of 3.44 g/cm³.
Positive
- High-purity nanoscale powder: 99.5% purity with 20-35 nm particle size enables controlled evaporation and consistent film stoichiometry for thin-film applications.
- Multiple pack size options: Available in 25g, 100g, 500g, and 1kg packs, allowing flexible procurement scaling for R&D to pilot production without reordering.
Trade-offs
- E-beam evaporation preferred: Thermal evaporation requires RFQ feasibility confirmation; E-beam with compatible liner or high-temperature crucible is the recommended method, limiting deposition hardware flexibility.
- High melting point constraint: Melting point of 1,900°C necessitates specialized crucible materials and high-power E-beam sources, increasing infrastructure and operational complexity.
