15. The method according to claim 14, wherein the non-swelling phyllosilicates have one of the following chemical formulas:

(SixGe(1-x))4M3O10(OH)2,  (I) in which:

x is a real number of the interval [0; 1], and
M denotes at least one divalent metal having the formula Mgy1Coy2Zny3Cuy4Mny5Fey6Niy7Cry8; each index y1, y2, y3, y4, y5, y6, y7 and y8 representing a real number of the interval [0; 1], and such that Σi=18yi=1,, or

(Aly′M′(1-y′))2(Six′Ge(1-x′))2O5(OH)4,  (II) in which:

M′ denotes at least one trivalent metal chosen from the group formed of gallium
and rare earths,
y′ is a real number of the interval [0; 1], and
x′ is a real number of the interval [0; 1],, or

At(Six″Ge(1-x″))4M″kO10(OH)2,  (III) in which:

A denotes at least one monovalent cation of a metal element having the formula Liw1Naw2Kw3Rbw4Csw5, each w1, w2, w3, w4 and w5 representing a real number of the interval [0; 1] such that Σi=15wi=1,
x″ is a real number of the interval [0; 1],
M″ denotes at least one divalent metal having the formula Mgj1Coj2Znj3Cuj4Mnj5Fej6Nij7Crj8; each index j1, j2, j3, j4, j5, j6, j7 and j8 representing a real number of the interval [0; 1], and such that Σi=18ji=1,

k is a real number in the range [2.50; 2.85], and
t+2 k is a real number of the interval [5.3; 6.0].
