<P>PROBLEM TO BE SOLVED: To provide a production method of fine alkali metal niobate particles in a liquid phase system, wherein the size and shape of fine alkali metal niobate particles can be controlled, and to provide fine alkali metal niobate particles which have a controlled shape and size. <P>SOLUTION: A method for producing particles of sodium-potassium niobate represented by formula (1): Na<SB>x</SB>K<SB>(1-x)</SB>NbO<SB>3</SB>is provided, including four specific steps, wherein, as an alkali solution, a high concentration alkali solution containing Na<SP>+</SP>ions and K<SP>+</SP>ions is used. Sodium-potassium niobate particles which have a controlled size and shape are obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT |
