Differences Between Silicon Metal 1101 and Ferro Silicon 75
| Feature | Silicon Metal 1101 | Ferro Silicon 75 |
|---|---|---|
| Composition | At least 99% silicon, low impurities | About 75% silicon, about 25% iron, trace elements |
| Primary use | Semiconductor, solar cells, aluminum alloys | Steelmaking, cast iron, welding fluxes |
| Carbon content | 0.1% max | 0.2% max |
| Production process | Carbothermic reduction of silica, refined | Reduction of quartz with coke in furnaces with iron input |
| Purity level | Ultra-high purity for specialized industries | Balanced silicon-iron ratio for industrial processes |
What Does the 1101 Designation Mean?
The 1101 designation specifies tight impurity limits of about 0.1% Fe, 0.1% Al, and 0.01% Ca, which is what makes it suitable for high-purity applications.
Silicon Metal 1101 and Its Applications
Silicon Metal 1101 is a high-purity elemental silicon product: it is a raw material for aluminum alloys, silicones and silanes, polysilicon, and electronic applications, where impurity control is critical.
What Is Ferro Silicon 75?
Ferro Silicon 75 is an iron-silicon alloy: it is used in steelmaking as a deoxidizer and silicon-alloying agent and in foundry work for inoculation, where the iron content is part of the intended composition.
