| titleOfInvention | Method of obtaining zirconium dioxide stabilized with calcium oxide |
| abstract | 1. A method for producing zirconium dioxide, stabilized by calcium oxide, including co-precipitating zirconium and calcium from solutions of their compounds with an aqueous solution of ammonia, separating, drying and dispersing the dried mass. re-separation, drying and calcination of the precipitate, that is, in order to increase the homogeneity of the final product by chemical and phase composition, precipitation is carried out with the addition of ammonium carbonate or ammonium oxalate, and dispersion carried out with a caustic soda solution. 2, a method according to claim I, characterized in that the ammonia solution is taken in an amount necessary for precipitating zirconium, and ammonium carbonate or oxalate is in excess of 30-50% of stoichiometry for precipitating calcium. Zo The method according to claims. 1 and 2, about 1 ml (based on using an aqueous solution of caustic soda concentration of 6-8% and dispersing is carried out in an ultrasonic field. 00 |
