METAL ELEMENT STABILIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for stabilizing metal elements more stably to a stabilization agent.

SOLUTION: The stabilization method of metal element is expressed by the general formula RZr2(PO4)3(where R indicates H, H3O or NH4cation) and is a method for stabilizing one or more kinds of metal elements M to crystalline zirconium phosphate expressed by a formula 4ZrO23P2O5as an oxide by analytic calculation. The method includes a first process for controlling mixture liquid containing the crystalline zirconium phosphate and metal ion Mn+of the metal element (where n indicates average variance of the metal element M), and a second process for heat treating the mixture liquid over 100 °C.
