Versuchsvorschrift

That is, an oxychloride having a tetravalent metal such as zirconium, titanium or tin as a constituent element, for example, zirconium oxychloride, titanium oxychloride or tin oxychloride is added to a concentrated aqueous phosphoric acid solution, and after refluxing under heating for 24 hours, the precipitate is subjected to filtration, washing with water, drying and grinding to obtain a phosphate such as zirconium phosphate [Zr(HPO4)2.H2O]. This phosphate is immersed in an aqueous solution which contains an antimicrobial metal at a suitable concentration, thereby to obtain the phsophate of the present invention.
