Abstract:  The effect of LiF, LiOH, and Li₂CO₃ on the stability of tricalcium silicate was investigated at 1450°C. It was found by chemical analysis, X-ray phase analysis, and infrared spectral analysis that an addition of LiF stabilized tricalcium silicate while an addition of LiOH and Li₂CO₃ induced the decomposition of tricalcium silicate into dicalcium silicate and CaO. The opposite views concerning the intensifying effect of lithium appearing in literature may be due to the different effect of lithium salts with different anions.
