THE EFFECTS OF IMPURITIES ON LIME QUALITY

Magnesium Oxide (MgO) is a problem in high calcium lime as it affects the reactivity of the lime. The dissociation temperatures (temperature when CO2 is driven off) for high calcium oxide is about 898°C, while magnesium oxide is about 760°C. This makes the magnesium oxide "hard burned" and therefore, slow slaking and less active.
