PURPOSE: To obtain solid dispersions of acid salts of tetravalent metals having a lamellar structure in an inert. inorg. matrix by inserting the acid salts of the tetravalent metals having the lamellar structure between layers of an amine and heat-treating the same after a specified treatment.
CONSTITUTION: The prepn. of the solid dispersions of acid salts of tetravalent metals having the lamellar structure consisting of subjecting the acid salts of the tetravalent metals having the lamellar structure to interlayer peeling by inserting these acid salt between the layers of the amine, is executed in the following manner: The acid salts of the tetravalent metals inserted into the layers are dispersed into the medium selected from a colloidal soln. of gelatinizable inorg. materials and an aq. soln. of the oligosilicate prepd. by hydrolysis of the tetraalkyl silicate in an aq. tetraalkyl ammonium hydroxide soln. The resulted dispersion of the tetravalent metals is gelatinized and is subjected to washing with water, followed, if necessary, by drying and is heat treated at 80 to 650°C, by which the objective solid dispersion of the acid salts of the tetravalent metals is obtd.
