  • Patent number: 9528048
    Abstract: The present invention relates to a method for preparing hierarchically ordered structures of inorganic phosphate particles, homogeneously deposited on the surface of a phyllosilicate, which is characterized in that it comprises the following steps: a) obtaining an acid solution of precursor compounds of an inorganic phosphate; b) preparing a dispersion of particles of a phyllosilicate in aqueous medium and acidifying the phyllosilicate dispersion by adding at least one acid, thereby obtaining an acid dispersion; c) mixing the acid solution obtained in step a) with the dispersion obtained in step b); and d), with stirring, adding a base to the mixture obtained in step c) until the required pH value for precipitating the corresponding inorganic phosphate on the phyllosilicate particles has been achieved, resulting in a hierarchically ordered structure of homogeneously distributed submicrometric or nanometric inorganic phosphate particles supported on the phyllosilicate surface.
