[0021] First, weigh 3kg of pig bones, place them in a drying oven, and dry them at 110°C until they reach a constant weight. Then put the dried pig bones into a pulverizer to grind them, pass through a 100-mesh sieve, and place the sieved animal bone powder in a In a muffle furnace, heat to 700°C, heat-preserve and calcinate for 2 hours. After cooling to room temperature, wash the calcined product 5 times with deionized water, and dry naturally to obtain natural porous hydroxyapatite powder; then weigh 7.5g of aluminum sulfate , add 100mL deionized water, stir at 400r / min for 30min, heat to 40°C, then add 36mL of 5% sodium hydroxide solution dropwise at 2mL / min, continue to stir for 2h after the dropwise addition, cool to room temperature and then statically Set aside for 2 hours to obtain an aluminum-based sol; then weigh 200g of natural porous hydroxyapatite powder and add it to 600mL of absolute ethanol, stir at 400r / min for 30min, then add the obtained aluminum-based sol, a...

[0023] First weigh 2kg of fish bones, place them in a drying oven, and dry them at 105°C until they reach a constant weight. Then put the dried animal bones into a pulverizer and grind them, pass through a 100-mesh sieve, and place the sieved animal bone powder in a In a muffle furnace, heat to 600°C, heat-preserve and calcinate for 1 hour. After cooling to room temperature, wash the calcined product 3 times with deionized water, and dry naturally to obtain natural porous hydroxyapatite powder; then weigh 5.0 g of aluminum sulfate , add 80mL of deionized water, stir at 300r / min for 20min, heat to 35°C, then add 24mL of 5% sodium hydroxide solution dropwise at 1mL / min, continue to stir for 1h after the dropwise addition, cool to room temperature and stand still Set aside for 1 hour to obtain an aluminum-based sol; then weigh 100 g of natural porous hydroxyapatite powder and add it to 500 mL of absolute ethanol, stir at 300 r / min for 20 minutes, then add the obtained aluminum-bas...

[0025]First weigh 2.5kg of animal bone, place it in a drying oven, and dry it to constant weight at 107°C, then put the dried animal bone into a pulverizer and grind it, pass through a 100-mesh sieve, and place the sieved animal bone powder in a In a muffle furnace, heat to 650°C, heat-preserve and calcinate for 1 hour. After cooling to room temperature, wash the calcined product 4 times with deionized water, and dry naturally to obtain natural porous hydroxyapatite powder; then weigh 6.2 g of sulfuric acid Aluminum, add 90mL of deionized water, stir at 350r / min for 25min, heat to 37°C, then add 30mL of 5% sodium hydroxide solution dropwise at 1mL / min, continue stirring for 1h after the dropwise addition, and cool to room temperature Stand still for 2 hours to obtain aluminum-based sol; then weigh 150g of natural porous hydroxyapatite powder and add it to 550mL of absolute ethanol, stir at 350r / min for 25min, then add the obtained aluminum-based sol, and react for 2 hours in a ...
