In principle, this is a fast and energetic reaction, but precipitation of an insoluble layer of hydrated iron oxide upon the calcium aluminoferrite crystal surface forms a barrier to further reaction. The ferrite, like tricalcium aluminate, hydrates to hydrogarnet: Ca 4 Al 2 Fe 2 O 10 + 7H 2 O → Ca 3 (Al(OH) 6 ) 2 + Fe 2 O 3 + Ca(OH) 2 In this case, the precipitation of insoluble iron oxide on the crystal surface protects it from further reaction - the ferrite is "self-passivating".
