ABSTRACT:
The present invention provides a crystalline layered zirconium phosphate, which is an ion exchanger particle excellent in heat resistance and chemical resistance, and utilizable as an impurity ion trapping agent for electronic materials, a raw material for antibacterials, a deodorant, a discoloration inhibitor, a rust preventive and the like, and which is also excellent in various processabilities.As a result of exhaustive studies to solve the problems, the present inventor has found a novel layered zirconium phosphate represented by the general formula (1) shown below:in-line-formulae description="In-line Formulae" end="lead"?Zr1-xHfxHa(PO4)b.nH2O (1)in-line-formulae description="In-line Formulae" end="tail"?wherein a and b are positive numbers satisfying 3b−a=4; b is a number satisfying 2<b≦2.3; x is a positive number satisfying 0≦x<1; and n is a positive number satisfying 0≦n≦2,and thus has achieved the present invention.
