What are the guaranteed chemical and phase specifications for Atomfair Silicon Nitride (Si3N4) Ceramic Powder?
The powder is supplied as a 3N (99.9% purity) grade with alpha phase <20%, D50 5–10 μm, nitrogen ≥38%, carbon ≤0.15%, oxygen <1.0%, iron ≤5000 ppm, aluminum ≤2500 ppm, and calcium ≤2500 ppm. These values are explicitly stated in the product specification for this silicon nitride ceramic powder.
Why is the alpha-phase content specified as <20% for this Si3N4 powder?
The product is described as a silicon nitride ceramic powder with a defined low alpha-phase proportion of <20%. It is intended for silicon nitride ceramic processing and formulation research; the source does not state a specific phase-transformation or sintering performance benefit beyond that application scope.
What documentation and customization options are available for this Si3N4 powder?
COA and SDS can be provided upon request for batch-specific confirmation. Custom specifications, quantities, and packaging may also be available upon request, with minimum order quantities, pricing, and lead times confirmed during technical review and quotation.
Atomfair 3N Si3N4 ceramic powder is assessed for silicon nitride ceramic processing and formulation research based on its specified alpha-phase <20%, D50 5–10 µm particle-size range, and defined N, O, C, Fe, Al, and Ca composition limits. The low alpha-phase fraction and micron-scale particle-size distribution make this a process-specific starting material that requires phase and lot-chemistry verification before selecting a sintering route.
Positive
- Defined low alpha-phase proportion: Alpha phase <20% is explicitly specified, giving researchers a controlled phase-composition baseline for silicon nitride ceramic processing and formulation trials rather than an uncharacterized mixed-phase powder.
- Traceable chemistry and documentation: Nitrogen ≥38%, oxygen <1.0%, carbon ≤0.15%, and Fe/Al/Ca impurity limits are stated, with COA and SDS available for batch-specific composition confirmation before formulation work.
Trade-offs
- Non-alpha-dominant phase distribution: Because alpha phase is specified below 20%, processes that depend on alpha-phase content for sintering behavior or phase-transformation routes must verify whether this starting phase distribution is suitable for their intended ceramic properties.
- Permitted impurity levels must be checked: With iron up to 5000 ppm and aluminum and calcium up to 2500 ppm each, users targeting high-purity sintered ceramics should confirm through the COA that the actual lot values meet their process tolerance before scale-up.
