실험 절차

Oxalic acid is added to an aqueous solution of zirconium oxynitrate and sodium nitrate with stirring and phosphoric acid is further added thereto. This is adjusted to a pH of 3.5 with aqueous sodium hydroxide solution and is refluxed under heating for 78 hours and the precipitate is subjected to filtration, washing with water, drying and grinding to obtain zirconium phosphate [NaZr2 (PO4)3 ] of network structure. This zirconium phosphate is immersed in an aqueous solution containing an antimicrobial metal at a suitable concentration to obtain the phosphate of the present invention which has network structure.
