There are errors in the expression of Eqs. [9] and [11], and Reference 24 in the published article.

Equation [9] should be:

$$ \left( {\text{CaS}} \right)\mathop{\longrightarrow}\limits^{\text{Oxygen}}\; \left[ {\text{Ca}} \right] + \left[ {\text{S}} \right] $$

Equation [11] should be:

$$ \left[ {\text{Ca}} \right] + \left( {x + {1 \mathord{\left/ {\vphantom {1 3}} \right. \kern-0pt} 3}} \right)\left( {{\text{Al}}_{2} {\text{O}}_{3} } \right) = {\text{CaO}} \cdot x{\text{Al}}_{2} {\text{O}}_{3} + {2 \mathord{\left/ {\vphantom {2 3}} \right. \kern-0pt} 3}[{\text{Al}}] $$

Reference 24 should be:
