Ferro silicon barium, also known as silicon barium, is a widely used ferroalloy in the steel and foundry industries. Depending on the barium content, ferro silicon barium can be categorized into high barium ferro silicon barium (FeSiBa30) and low barium ferro silicon barium (FeSiBa2-3 or FeSiBa4-6). This material plays a crucial role in industrial applications, especially in deoxidation, desulfurization, and casting processes.
Ferro Silicon Barium Specification
Ferro silicon barium inoculant is a ferrosilicon based alloy containing a certain amount of barium and calcium. Its main features are:
- Increases Graphitization Nucleus: Refines graphite and promotes the formation of A-type graphite in gray iron and spherical graphite in ductile iron, improving the nodulization degree.
- Reduces White Cast Iron Tendency: Lowers relative hardness, improving machinability.
- Strong Anti-Decaying Ability: Prevents inoculation and nodulization decay.
- Improves Fracture Uniformity: Reduces shrinkage tendencies.
- Stable Chemical Composition: Uniform granularity, small deviations in composition and quality.
- Low Melting Point: Melting point close to 1300°C, easy to melt during inoculation treatment with minimal slag.

Production and Application of Ferro Silicon Barium
FeSiBa Production Process
Ferro silicon barium is primarily produced by smelting ferro silicon and barium iron. High barium ferro silicon barium can be melted in a medium-frequency furnace and then aluminum is added to prepare ferro silicon barium aluminum alloy, which is used for final deoxidation in steel production.
FeSiBa Main Applications
- Deoxidizer and Desulfurizer: The barium in the silicon barium alloy has a strong affinity for oxygen and sulfur, effectively removing harmful substances from steel and improving the morphology of inclusions.
- Inoculant in the Foundry Industry: As an inoculant, silicon barium is used in the production of gray iron and ductile iron, promoting A-type graphite and enhancing the nodulization level, thereby improving the performance of castings.
- Advantages of Silicon Barium Inoculant: Silicon barium inoculant is highly active and is an effective long-term inoculant in cast iron production. One ton of silicon barium alloy can economically replace 1.5 tons of ferrosilicon. It is suitable for gray iron and ductile iron, with high utilization rates and strong desulfurization capabilities, superior to silicon calcium alloys.
