<P>PROBLEM TO BE SOLVED: To provide a production method capable of obtaining at a high yield, crystalline layered zirconium phosphate utilizable for various applications. <P>SOLUTION: It is found that layered zirconium phosphate equivalent to the case of using a new raw material can be produced from phosphoric acid, a recovered filtrate in a wet synthesis method using a zirconium raw material, and reaction liquid containing at least either of phosphoric acid and the zirconium raw material and an organic acid, and that utilization efficiency of the raw material contained in the recovered filtrate can be remarkably improved to reduce waste. <P>COPYRIGHT: (C)2013,JPO&INPIT |
