Ferrosilicon briquette
Aliases: FeSi briquette · Steelmaking ferrosilicon ball
A steelmaking silicon source made principally from verified ferrosilicon fines by batching, binding, briquetting and curing or drying. After finished-product chemistry, effective silicon, moisture, strength and plant recovery are validated, it may be used for tapping deoxidation, silicon alloying and selected slag-reduction duties; it is not silicon-slag briquette, silicon-carbon briquette or lump ferrosilicon.
Silicon metal
Industrial silicon controlled by Si, Fe, Al, Ca and application-specific trace elements. After technical review it can be used in aluminium alloying and as upstream feed for silicones or further purification to polysilicon; actual grade, sizing and documents must be confirmed by application.
Silicon metal powder
Aliases: Silicon-metal powder for refractories (application grade) · Crystalline silicon powder for carbon-containing refractories · Silicon-metal powder for reaction-bonded silicon carbide
Crystalline silicon-metal powder produced by crushing, milling and classifying industrial silicon. Particle-size distribution, impurities, reactivity and dust hazards vary with feedstock, milling route and application. After technical review it may be used in carbon-containing refractories, dedicated SiSiC/RBSiC processes or direct silicone synthesis. Formal supply is governed by the actual SKU TDS, SDS/PSI and lot COA.
Calcium silicon alloy
Used for technically reviewed deoxidation, calcium treatment and inclusion control in steelmaking and steel foundries; performance depends on grade, deoxidation state, sulfur, feed form and process stage.
Silicon aluminium alloy
Aliases: Ferrosilicon-aluminium alloy
A silicon-and-aluminium composite direction for deoxidation and chemistry adjustment in reviewed steelmaking and cast-steel practices; Si/Al ratio, residuals and timing must match the target grade.
Silicon barium alloy
Can be managed as a reviewed silicon-barium inoculant for cast iron or as a compound steel deoxidizer; Ba/Si system, sizing, addition point and acceptance criteria must remain application-specific.
Silicon-carbon alloy
A commercial family of steelmaking additions whose principal declared control variables are silicon and carbon. Depending on the confirmed SKU, it may be a smelted material or an agglomerated composite; after process review it may support combined Si/C adjustment, deoxidation practice or heat-balance trials. Phase constitution, chemistry, residuals, sizing, recovery and addition practice must be confirmed by the formal TDS, lot COA and plant trial.
Refractory-grade ferrosilicon powder
Aliases: Ferrosilicon antioxidant powder for refractories · Refractory-grade FeSi fine powder
A refractory-application fine-powder family made from composition-confirmed ferrosilicon through controlled crushing, milling, classification, homogenisation, sampling and moisture-protected packing. It may serve as an antioxidant addition in validated carbon-containing refractory formulations such as MgO-C. Chemistry, sizing, surface condition and use require a formal TDS, powder SDS/PSI, lot COA and finished-product trials.
Industrial silicon for infiltration
Aliases: RBSiC / SiSiC silicon-infiltration feed · Silicon feed for reaction-bonded silicon carbide
An industrial-silicon application family for RBSiC / SiSiC reaction bonding or silicon infiltration. Confirmed sizing, fines, Fe/Al/Ca and application-specific residuals, melting and infiltration behaviour must match the porous SiC-C body. This page is neither a separate chemical grade nor a stock claim.
FeSi-based inoculant
This page explains the product's principal composition, application directions and inquiry points; confirm the grade, guaranteed indicators, sizing, packing and process fit before quotation.
Rare-earth Ferrosilicon Magnesium Alloy (Nodulariser)
A magnesium treatment alloy for ductile iron; grade, size and quantity depend on base-iron S/O, temperature, treatment ladle and target residual Mg.
Si+CProduct form reference
High-carbon silicon
Aliases: Silicon-carbon alloy (identity must be verified) · Silicon Recarb (market term)
High-carbon silicon is a market term that may refer to a smelted alloy, furnace-bottom recovered and sorted material, or a formed blend of silicon- and carbon-bearing fines. An inquiry must first establish the actual production route, phases, total Si/C, residuals, form and addition point.
Si-Mg?Product form reference
Silicon-magnesium inoculant
Aliases: Magnesium-bearing ferrosilicon inoculant (application and grade to verify)
The Mg, Si, Ca, rare-earth balance, particle size and exact inoculation duty must be confirmed to avoid confusion with nodularisers.
