Reaktionsschritte
Hydroxylapatite in an amount of 1.0 kg is added to 10 liters of water together with 32 g of silver nitrate and 69 g of zinc nitrate, and then the whole was stirred to make a reaction. The solids are separated off to form a cake, then the cake is rinsed thoroughly with distilled water and dried. The washed cake is heated or fired at 1200° C. and powdered to provide the antibacterial hydroxylapatite carrying about 2% by weight of silver in a metallic state and 1.5% by weight of zinc in a metallic state.
