Title:
合成鉱物粒子の調製方法
Document Type and Number:
Japanese Patent JP6885956
Kind Code:
B2
Abstract:
The invention relates to a method for preparing synthetic mineral particles with formula (AlyM1-y)2(SixGe1-x)2O5(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 (AlyM1-y) to (SixGe1-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.
