Atomfair High-Purity Silicon Nitride (Si₃N₄) Ceramic Powder (SKU AF-FM-C-SNIT-3FHJ-SP00) is a 3N-grade, alpha-phase ≥90% powder with D50 <0.9 μm, designed for silicon nitride ceramic substrate and high-power module packaging research. Its controlled impurity limits (Fe, Al, Ca ≤200 ppm each) and defined particle size support reproducible sintering and densification studies, though the fine particle size and high surface area require careful handling to prevent agglomeration and moisture uptake.
Positive
- High alpha-phase content: Alpha phase ≥90% provides the reactive precursor necessary for controlled phase transformation to beta-Si₃N₄ during sintering, enabling dense, high-strength ceramic substrates.
- Controlled impurity profile: Fe, Al, and Ca each ≤200 ppm, with free silicon <0.2% and carbon ≤0.10%, minimizes secondary phase formation and dielectric loss in high-power module packaging applications.
Trade-offs
- Fine particle handling sensitivity: D50 <0.9 μm results in high specific surface area, increasing risk of agglomeration and requiring controlled dispersion protocols or milling steps for uniform green body formation.
- Moisture and oxidation susceptibility: Oxygen content ≤1.4% and the fine powder form necessitate storage in dry, inert conditions to prevent surface oxidation and hydrolysis, which can alter sintering behavior.
