For example, silicate liquid bridges will be formed by adding CaO into iron ore pellets [14,15,16], which is one of the reasons why the compressive strength and reduction-softening behavior are improved [17,18,19,20,21], but a maximum swelling index still exists in the basicity range of 0.2–0.6 . In addition, more CaO need to be added to …
