Abstract

Spherical basic zirconium sulphate particles were prepared by homogeneous precipitation in mixed solutions of zirconium sulphate and urea. Values of [SO₄^2-]/[Zr⁴⁺] and [urea]/[Zr⁴⁺] in starting mixed solutions and cooling rate may affect the formation of spherical particles. Complexes such as [Zr(OH)_n]^4-n could prevent the formation and thus lead to gel precipitation. In addition, spherical particles could only be obtained in the presence of SO₄^2-; for NO^3- and Cl^-, only gel precipitation occurred.
