Résumé : A study has been made of the reactions in the solid state between Ca(OH)2 and bayerite on the one hand, and between CaO and Al2O3 on the other, by preparing mixtures of these compounds and maintaining them at constant temperatures (110°, 400°, 900°, 1000°, 1100°, 1200°, 1250° and 1300° C). The samples were investigated by means of X‐ray analysis, dilatometry and chemical analysis. It is shown that, as the temperature reaches 1000° C and then increases, there is first formed the aluminate with the highest Al2O3 content, followed by one with a lower content and finally by that one which has the lowest Al2O3 content. On the basis of these results, the author proposes a mechanism for the reaction in the solid state between Al2O3 and CaO which is shown schematically (fig. 9).
