Abstract:
The invention relates to a method for preparing synthetic mineral particles with formula (Al y M 1-y ) 2 (Si x Ge 1-x ) 2 O 5 (OH) 4 , wherein M designates at least one trivalent metal selected from the group made up of gallium and the rare earths, which comprises the following steps: preparing a gel which is a precursor of said synthetic mineral particles by a co-precipitation reaction of at least one salt of metal selected among aluminium and M with at least one silicon source selected from the group made up of potassium metasilicate, sodium metasilicate, potassium metagermanate and sodium metagermanate, the molar ratio of (Al y M 1-y ) to (Si x Ge 1-x ) during the preparation of said precursor gel being equal to 1, at least one base being added during said co-precipitation reaction; and performing a solvothermal treatment of said precursor gel at a temperature of 250° C. to 600° C.

Claim (Index 1):
Method for preparing synthetic mineral particles of the following formula (I):\n (Al y M 1-y ) 2 (Si x Ge 1-x ) 2 O 5 (OH) 4 \u2003\u2003(I) in which\n Al indicates aluminium, \n Si indicates silicon, \n M indicates at least one trivalent metal selected from the group of gallium and the rare earth elements, \n y is a real number between 0 and 1, \n Ge indicates germanium, \n x is a real number between 0 and 1, \n O indicates oxygen, and \n H indicates hydrogen, \n method wherein:\n a precursor gel of the synthetic mineral particles of formula (I) is prepared by means of a co-precipitation reaction between:\n at least one salt of a metal selected from the group of aluminium and M, \n at least one source of at least one chemical element selected from the group of silicon and germanium, said source of the chemical element selected from the group of silicon and germanium being selected from the group consisting of potassium metasilicate, sodium metasilicate, potassium metagermanate, and sodium metagermanate, \n the molar ratio of (Al y M 1-y )/(Si x Ge 1-x ) over the course of the preparation of the precursor gel being equal to 1, \n at least one base being added over the course of the co-precipitation reaction, \n \n said precursor gel is subjected to continuous solvothermal treatment at a temperature between 250 and 600\u00b0 C. for a period selected so as to allow synthetic mineral particles of formula (I) to be obtained.
