Is silicon better than steel?‌

Silicon itself is a brittle metalloid and is not "better" than steel for structural applications. However, adding silicon to steel creates silicon steel (an Fe-Si alloy), which exhibits superior soft magnetic properties (high permeability, low core loss) and higher electrical resistance compared to ordinary steel or pure iron. This makes silicon steel vastly superior for electromagnetic cores in transformers and motors, though it has lower ductility than plain iron. Pure silicon has different applications (e.g., semiconductors).

Where is ferro silicon used?‌

Ferrosilicon is predominantly used in the production of electrical steels (both oriented and non-oriented silicon steels). These steels are essential core materials in electrical equipment, including transformers, generators, electric motors (especially critical for modern applications like electric vehicle drive motors), and inductors.
