Abstract

A soluble basic zirconium sulphate is produced by heating under superatmospheric pressure zirconium dioxide, sulphuric acid and water, the molar ratio of said mixture being from 2:3:0.7 to 2:3:3. By adding sulphuric acid to dissolve said sulphate and make the resulting solution strongly acid, and allowing the solution to stand, Zr(SO4)2.4H2O operates as a crystalline precipitate. The reaction of the oxide with sulphuric acid preferably is carried out at 300-380 DEG C. and the autogeneous pressure is normally employed, in examples by the use of a bomb. Pressures of 2-80 ats. are mentioned. After treatment of the basic product with concentrated sulphuric acid and separation of the hydrated sulphate, the resulting liquid can be diluted and reused to form more of the basic salt and thus avoid loss of zirconium material. Unconverted ZrO2 can be recovered by refurnacing. Examples of the invention are given, and a comparative example discloses the use of a ZrO2:H2SO4:H2O rati of 1:2:2.
