Abstract

Process for the preparation of broadly pure zirconium oxide from zirconium silicates, such as zirconium sand, characterized in that the zirconium silicates are unfolded or thermally dissociated without additives in a manner known per se, and is extracted by leaching, the finely granulated material, under agitation for about 2 to 10 hours, preferably 6 to 8 hours, with an aqueous alkaline solution, preferably containing 10 to 50% by weight of sodium hydroxide or 14 to 70% by weight of potassium hydroxide or corresponding mixtures of hydroxides, at temperatures between 60 and 110º c, the molar ratio of alkali hydroxide to s102 rises to 0.5-4.1, preferably to 1 to 2: 1.
