摘要：

Formation region of γ-zirconium phosphate (γ-ZrP) is determined by using zirconium phosphate gels heated in phosphate solutions with various pH values. Sodium ions in the phosphate solutions play an important role in the formation of γ-ZrP. It is formed in the pH region where the protons of zirconium phosphate gels are partly exchanged with sodium ions. The crystal lattice parameters of γ-ZrP are determined to be a = 5.376±0.002 A ̊. b = 6.636 ± 0.004 A ̊, c = 24.56 ± 0.01 A ̊ and ß = 93.94 ± 0.05°. A possible structural model for the crystal is proposed, in which ZrO6 octahedra and PO3(OH) tetrahedra are more densely linked by corners than in the known structure of α-ZrP. © 1979.
