摘要

PROBLEM TO BE SOLVED: To provide a lamellar titanic acid, a layered titanic acid as a starting material of the lamellar titanic acid, a lamellar titanium oxide obtained from the lamellar titanic acid which can be produced without requiring a special equipment, have a large particle diameter/thickness ratio and show good dispersibility, and also to provide a method for producing the lamellar titanic acid.;SOLUTION: The layered titanic acid is obtained by subjecting a layered titanate represented by formula: A_XM_Y__ZTi_2-(y+z)O₄, wherein A or M represents metals having a valence of 1 to 3 and being different from each other, _ represents a defect to be occupied by Ti, x is a positive real number satisfying 0x1.0, y and z are respectively 0 or positive real number satisfying 0y+z1.0, to an acid treatment, to thereby substitute hydrogen ions or hydronium ions for 40-99% of A and/or M ions, the lamellar titanic acid is obtained by reacting the layered titanic acid with a basic compound, to thereby delaminate the layered titanic acid, and the lamellar titanium oxide is obtained by subjecting the lamellar titanic acid to a heat treatment or the like.;COPYRIGHT: (C)2009,JPO&INPIT
