Abstract

Das Verfahren zur Herstellung von Calciumhydroaluminat besteht darin, dass das Reaktionsmittel, das Aluminiumoxid enthaelt, mit Kalk versetzt und das erhaltene Faellproduktion mit heissem Wasser gewaschen wird; danach wird das Faellprodukt bei 290-510C 1-10 Stunden lang einer thermischen Behandlung unterzogen.The method of producing calcium hydroaluminate is to lime the reaction agent containing alumina and to wash the resulting well production with hot water; Thereafter, the product is subjected to thermal treatment at 290-510C for 1-10 hours.
