Abstract
(EN)
Provided is a method for preparing a calcium aluminate inorganic material. The method for preparing a calcium aluminate inorganic material may comprise the steps of: mixing a first source material comprising calcium oxide (CaO) and a second source material comprising aluminum oxide (Al2O3) to prepare a base source; and heat-treating the base source to prepare a calcium aluminate-based inorganic material comprising a first calcium aluminate inorganic material, and a second calcium aluminate inorganic material having a higher aluminum oxide content than the first calcium aluminate inorganic material.
(FR)
L'invention concerne un procédé de préparation d'une matière inorganique d’aluminate de calcium. Le procédé de préparation d'une matière inorganique d'aluminate de calcium peut comprendre les étapes consistant à : mélanger une première matière source comprenant de l'oxyde de calcium (CaO) et une seconde matière source comprenant de l'oxyde d'aluminium (Al2O3) pour préparer une source de base ; et traiter thermiquement la source de base pour préparer une matière inorganique à base d'aluminate de calcium comprenant une première matière inorganique d'aluminate de calcium, et une seconde matière inorganique d'aluminate de calcium ayant une teneur en oxyde d'aluminium supérieure à celle de la première matière inorganique d'aluminate de calcium.
