History

Increased crucible silicon dioxide causes which impediment within early steel production?

A)Reduced carbon diffusion rate uphill
B)Oxide eutectic melting point depression
C)Increased refractory lining degradation risk
D)Promotion of homogeneous alloy nucleation

💡 Explanation

Increased silica (SiO2) in a crucible reacts with iron oxides creating slag; therefore, accelerated refractory lining degradation occurs because the acidic slag corrods the silicate-based crucible, rather than promoting desirable alloy formation.
