The authors begin again systematically the study of the formation of a phyllosilicate of phlogopite type from a mixture of opal and amagnesian hydrotalcite. Then, magnesian, nickeliferous and lithic hydrotalcites were prepared and associated with silicoalu-minous gels of different compositions. In presence of CO3K2 at 135°C, clay minerals of phlogopite type form effectively, except in the case of lithiniferous hydrotalcite. The composition of the products obtained shows that phyllo silicates can form by a simple combination of silica with the octahedral sheet of hydrotalcite. The latter must transform, if it be not dissolve, for the synthesis to be possible.Ayant constaté qu'un mélange d'opale et d'ydrotalcite magnésienne semblait permett...
