682 grams of a 60 percent aqueous solution of etidronic acid was added slowly to a stirred slurry of 400 grams zinc oxide in 1.45 Kg distilled water. A dense white amorphous precipitate was produced and settled when agitation had stopped to leave a clear liquor. The reaction was exothermic. The mixture was filtered and the precipitate was washed with distilled water and dried at 110° C. 863 grams of a zinc etidronate having a zinc to etidronate molar ratio of 2.4:1 was obtained.
