← HistoryWhich outcome results when blooming iron ore too rapidly in ancient Chinese iron production?
A)Increased slag inclusions remains within iron✓
B)Increased dissolved carbon improves strength
C)Phosphorus concentration reduces grain size
D)Silicon provides improved corrosion resistance
💡 Explanation
Incomplete reduction occurs during rapid bloomery processing because the solid-state diffusion mechanism is insufficient, therefore yielding more slag inclusions, rather than allowing sufficient time for refining the iron to control composition profile.
