Barium-Silicon Inoculant

2025-09-18

Barium-silicon inoculants are primarily used in the production of gray and ductile iron. When used in ductile iron, they significantly increase the number of graphite nodules; when used in gray iron, they reduce the tendency toward white cast iron, refine grains, promote graphitization, and improve graphite morphology. In addition to improving mechanical properties, barium-silicon inoculants also exhibit strong anti-fading properties. The most commonly used inoculant is one containing 2-4% barium. Barium-silicon inoculants are typically available in 0.2-0.8mm flow-through inoculants, with particle sizes ranging from 1-3mm to 3-8mm.
