EXFOLIATE STRUCTURED ZIRCONIUM PHOSPHATE, PRECURSORS OF SAID PHOSPHATE, METHOD FOR THE PRODUCTION AND USE THEREOF IN MACROMOLECULAR-MATERIAL-BASED COMPOSITIONS

摘要

The invention relates to an exfoliate structured zirconium phosphate characterized in that it is embodied in the form of a gel containing a maximum 1000 ppm organic compounds or a gel devoid of organic compounds which are chemically linked to phosphate. Said phosphate is obtained by a method wherein an aqueous dispersion is formed from a crystallized zirconium phosphate; a quantity of sodium compound is added to said dispersion whereby the NA/P ratio is more than 0.5; an acid is added in order to obtain a gel or a solid compound which is placed once more in water and which results in a gel. The phosphate can be used in the preparation of macromolecular-material-based compositions in order to improve the properties thereof.
