Ferro Silicon Barium

Application :
Inoculation is a process of controlling the structure and properties of cast iron by increasing the number of nucleation events during solidification. An inoculant is a material added to the hot metal just prior to casting which provides as suitable phase for nucleation of graphite during subsequent cooling process. The objective of inoculation is to provide enough nucleation sites for the carbon to precipitate as graphite instead of iron carbide(cementite, Fe3C)

Normal Barium(0.8-1.3%)
High Barium(1.8-2.0 %)

The inoculants with high Barium have higher fading time and are especially beneficial when pouring time is long. It find its special application in Cast Iron Inoculation
