What Is the Technical Data for Ferro Silicon Nitride?

 

The technical data for Ferro Silicon Nitride​ provides essential information about its chemical composition, physical properties, and performance characteristics, which are critical for its effective use in metallurgical applications.

 

Typical Chemical Composition (%):

•Silicon Nitride (Si₃N₄):​ 15% – 25%

•Iron (Fe):​ 35% – 45%

•Free Silicon (Si):​ 15% – 25%

•Nitrogen (N):​ 2% – 8%

•Aluminum (Al), Calcium (Ca), Sulfur (S), Phosphorus (P):​ < 1% each (depending on grade)

 

Physical Properties:

•Appearance:​ Grayish or greenish powder/granules

•Melting Point:​ > 1400°C (due to Si₃N₄ stability)

•Density:​ ~2.5 – 3.2 g/cm³ (varies with composition)

•Particle Size:​ Typically ranges from 100 mesh (150 μm) to 325 mesh (44 μm) for powder; granular forms are also available

•Thermal Stability:​ Highly stable at elevated temperatures without decomposition

 

Key Technical Features:

•Acts as a controlled nitrogen donor​ in molten steel

•Provides silicon for deoxidation

•Enhances grain refinement and nitride precipitation

•Offers excellent chemical and thermal stability

 

Technical datasheets from suppliers often include additional details such as moisture content, recommended dosage, handling instructions, and packaging information. These data points are crucial for metallurgists and foundry engineers to ensure proper application and performance in specific production environments.
