What phase purity, particle size, and chemical limits are specified for Atomfair 4N alpha silicon nitride powder?
Atomfair specifies alpha phase ≥90%, D50 ≤0.68 μm, and 4N (99.99%) purity. The powder also has nitrogen ≥37.5%, free silicon <0.2%, carbon ≤0.15%, and oxygen ≤3.0%, with iron ≤1800 ppm, aluminum ≤900 ppm, and calcium ≤900 ppm.
What is the intended application scope of this alpha-phase Si3N4 ceramic powder?
This powder is intended for ceramic materials and silicon nitride materials research. It is supplied as a gray powder with the stated alpha-phase and particle-size specifications, and custom specifications, quantities, and packaging may be available upon request.
Can I obtain batch-specific COA and SDS documentation for this silicon nitride powder?
Yes, COA and SDS can be provided upon request for batch-specific confirmation. Contact the manufacturer for technical support or official institutional quotations.
This Alpha Silicon Nitride powder provides a D50 of ≤0.68 μm with certified alpha phase ≥90%, making it a controlled starting material for ceramic and Si3N4 materials research. Oxygen ≤3.0% and trace-metal maxima are explicitly disclosed, so batch COA verification is recommended before impurity-sensitive sintering studies.
Positive
- Alpha-phase ≥90% for nitride ceramic research: The certified alpha-phase content of at least 90% provides a defined starting phase for evaluating phase transformation and silicon nitride material behavior.
- D50 ≤0.68 μm for fine powder processing: A D50 specification of ≤0.68 μm provides a fine starting powder for particle-size-sensitive ceramic processing studies.
Trade-offs
- Oxygen ≤3.0% affects sintering protocol design: The oxygen specification is ≤3.0 wt%; users should account for this when designing sintering atmospheres and densification studies. Batch COA values should be confirmed before use.
- Trace-metal maxima require COA confirmation: Fe ≤1800 ppm, Al ≤900 ppm, and Ca ≤900 ppm are stated upper limits; for applications with strict cation impurity tolerances, batch-specific COA data should be reviewed.
