Embodiment 1
[0047] with P 2 o 5 、Na 2 CO 3 , CaCO 3 , SrCO 3 , AgNO 3 as the raw material, and the glass oxide corresponding to each substance is P 2 o 5 、Na 2 O, CaO, SrO, Ag 2 O, mix the raw materials evenly, put them into the furnace, heat to 1300°C, keep warm for 2 hours to obtain a clear glass solution, then pour the glass solution into water to quench, collect glass particles, dry at 150°C, and grind, that is Obtain Ag and Sr bioglass sintering aid (composition is 45P 2 o 5 -20Na 2 O-15CaO-12SrO-8Ag 2 O);
[0048] β-tricalcium phosphate, bioglass sintering aid and polyvinyl alcohol powder were ball milled to obtain a homogeneous mixture, which was then dried at 80°C. The mass ratio of β-tricalcium phosphate to bioglass sintering aid is 80:20. Based on the total mass of β-tricalcium phosphate, bioglass sintering aid and polyvinyl alcohol as 100%, the mass percentage of polyvinyl alcohol is 2%.
[0049] Put the dried mixture into the mould, carry out compression moldin...
Embodiment 2
[0052] SiO 2 , CaCO 3 ,P 2 o 5 , Ga 2 o 3 , AgNO 3 , SrCO 3 As the raw material, the glass oxide corresponding to each substance is SiO 2 , CaO, P 2 o 5 , Ga 2 o 3 、Ag 2 O and SrO, mix the raw materials evenly, put them in the furnace, heat to 1400°C, keep warm for 2 hours to obtain a clear glass solution, then pour the glass solution into water to quench, collect glass particles, dry and grind to obtain Containing Ag, Ga and Sr bioglass sintering aids (the composition is 49SiO 2 -36CaO-2P 2 o 5 -5Ga 2 o 3 -2Ag 2 O-6SrO);
[0053] The calcium silicate, the bioglass sintering aid and the methyl cellulose are ball-milled to obtain a uniform mixture, and then mixed with water to obtain a mixture slurry. The mass ratio of calcium silicate and bioglass sintering aid is 85:15. Based on 100% of the total mass of calcium silicate, bioglass sintering aid and methyl cellulose, the mass percentage of methyl cellulose is 15%. Based on the total mass of calcium silicat...
Embodiment 3
[0057] with P 2 o 5 、Na 2 CO 3 , CaCO 3 , ZnO, CuO, AgNO 3 is the raw material, and the glass oxide corresponding to each substance is P 2 o 5 、Na 2 O, CaO, ZnO, CuO, Ag 2 O, mix the raw materials evenly, put them in the furnace, heat them to 1200°C, and keep them warm for 2 hours to obtain a clear glass solution, then pour the glass solution into water to quench, collect the glass particles, dry, and grind to obtain Ag-containing , Cu and Zn bioglass sintering aids (composition is 50P 2 o 5 -25Na 2 O-15CaO-6ZnO-4CuO-5AgO);
[0058] Adding hydroxyapatite, β-tricalcium phosphate and biological glass sintering aid into polyvinyl butyral solution, and obtaining uniform mixture slurry after ball milling. The mass ratio of hydroxyapatite, β-tricalcium phosphate calcium carbonate and bioglass sintering aid is 35:55:10. The concentration of polyvinyl butyral was 7%. Based on 100% of the total mass of hydroxyapatite, β-tricalcium phosphate calcium carbonate, bioglass sinte...
