The possibilities of obtaining hydroxyapatite from meat industry

摘要: The goal of this work was investigation physical and chemical properties calcining products obtained from bone sludge. process carried out at the temperatures 873–1223 K, in chamber kilns air atmosphere. X-ray investigations phase composition confirmed that hydroxyapatite is main component products. phosphorus content these close to level concentration element typical phosphoric raw materials which proved right using waste meat industry as a substitute for materials. Studies morphology ashes different showed temperature did not affect product essential manner. In all cases fine-crystalline products, with similar shape size grain were obtained. Only calcined 1223 K characterized by slightly melted crystallites.
