Abstract A method for obtaining the oxysalt Na 6 Mg(SO 4 ) 4 by double reactions in Mg-Na 3 Al(SO 4 ) 3 mixtures is proposed. When the mixtures are calcinated at temperatures in the range 600–900 °C in an argon stream or an open atmosphere, a sodium-magnesium sulphate and alumina are obtained. A study of these double reactions has allowed us to establish that the mechanism of formation of the compound Na 6 Mg(SO 4 ) 4 is an exchange reaction between MgO and Na 3 Al(SO 4 ) 3 . In some cases… CONTINUE READING
