ZIRCONIUM PHOSPHATE AND METHOD FOR ITS PREPARATION

摘要

The invention relates to a zirconium phosphate in particles having sizes comprised within the range of from 1 to 100 mu m, a lamellar structure with interlayer distance, in the anhydrous state, comprised within the range of from 7.9 to 8.2 ANGSTROM and a surface area comprised within the range of from 9 to 20 m2/g. The method consists in altering the lamellar structure of a zirconium phosphate with layer structure of alpha type by intercalating into it an organic substance containing a proton-acceptor group and water and by a treatment with ultrasounds, in regenerating the hydrogen form of said zirconium phosphate by an acid and in washing the same with diluted acids and/or water.
