Cement Kilns: Clinker Minerals , n=0.25 is the maximum substitution, corresponding to a Na 2 O content of 5.7%. The often-quoted compound NaCa 4 Al 3 O 9 (n=0.33, Na 2 O 7.6%) and its potassium analogue are mythical. However the tricalcium aluminate in cement always contains many other elements. In particular, substitution of silicon in the aluminate structure allows more cations to be accommodated, and for the isomorphs in ...
