摘要
The invention relates to a process for the preparation of mixtures of synthetic, crystalline magadiite and salts which split off oxygen. For this purpose, 1 mol of soda-water glass which has a molar ratio of SiO. sub.2 :Na.sub.2 O=1:(0.25 to 0.5) is mixed with 0.1 to 0.9 mol of a compound which has a pH of less than 10.5 in molar aqueous concentration, as a neutralizing agent. In the presence of magadiite seed crystals, the reaction mixture is heated at temperatures from 373 to 523 K. in an autoclave for 1 to 15 hours and, after cooling, 0.15 to 1.5 mol of hydrogen peroxide are added per mol of soda-water glass employed. The solid and the dissolved substances are isolated from the reaction suspension as dry substance.
