Abstract
Phosphorus-free zirconium oxide, suitable for the manufacture of blue ceramic stains, is prepared by sintering zircon ore with the stoichiometric quantity or a slight excess of sodium or potassium carbonate, extracting the resulting sodium or potassium zirconyl silicate with a solution of sodium or potassium hydroxide and thereby removing phosphorus as soluble sodium or potassium phosphate, decomposing the sodium or potassium zirconyl silicate by treatment with hydrochloric acid, and subsequently converting the resulting zirconyl chloride into zirconium oxide by treating it with sulphuric acid and heating the resulting precipitate. Alternatively the ore may be sintered with an amount of sodium or potassium carbonate in excess of the stoichiometric quantity by at least 15% by weight, the resulting sodium or potassium zirconyl silicate extracted with water to remove sodium or potassium phosphate and then the acid decomposition proceeded with, as before. Blue ceramic stains may be manufactured by heating together a mixture of zirconium oxide, silica, ammonium metavanadate and sodium fluoride as described in Specification 625,448. Specification 627,493 also is referred to.
