Embodiment 1
[0038] Weigh 100 g of ZnO, 96 g of P 2 o 5 , 20 g Na 2 O, mix evenly in a high-speed mixer, then place in a ceramic crucible, and keep the temperature in a high-temperature furnace at 600°C for 1 hour to form a melt-like liquid, then slowly pour the melt into cold water to form a preliminary crushed antibacterial glass , and then take out the antibacterial glass and dry it in an oven at 100°C for 30 minutes to make it fully dry. Then utilize jet mill to pulverize it into antibacterial glass powder with average particle size less than 20 microns. The composition of antibacterial glass powder was analyzed by X-ray energy spectrum analyzer (EDX), and its composition was calculated according to the oxide component: ZnO 51wt%, P 2 o 5 39wt%,Na 2 O10wt%.
Embodiment 2
[0040] Weigh 373 grams of Zn(NO 3 ) 2 ·6H 2 O, 0.03 g AgNO3, 65 g P 2 o 5 , 55 g KH 2 PO 4 , mixed evenly in a high-speed mixer, then placed in a ceramic crucible, kept in a high-temperature furnace at 700°C for 45 minutes to form a melt-like liquid, and then slowly poured the melt into cold water to form a preliminary crushed antibacterial glass, Then take out the antibacterial glass and dry it in an oven at 100°C for 30 minutes to make it fully dry. Then utilize jet mill to pulverize it into antibacterial glass powder with average particle size less than 20 microns. The composition of antibacterial glass powder is analyzed by energy spectrum analysis, and its composition is calculated according to the oxide component: ZnO 51wt%, Ag 2 O0.01wt%,P 2 o 5 39.5wt%, K 2 O 9.49wt%.
Embodiment 3
[0042] Weigh 120 g of ZnC 2 o 4 .2H 2 O, 50 g P 2 o 5 , 31 g Na 2 CO 3 , mixed evenly in a high-speed mixer, then placed in a ceramic crucible, kept in a high-temperature furnace at 800°C for 30 minutes to form a melt-like liquid, and then slowly poured the melt into cold water to form a preliminary crushed antibacterial glass, Then take out the antibacterial glass and dry it in an oven at 100°C for 30 minutes to make it fully dry. Then utilize jet mill to pulverize it into antibacterial glass powder with average particle size less than 10 microns. The composition of antibacterial glass powder is analyzed by energy spectrum analysis, and its composition is calculated according to the oxide component: ZnO 52wt%, P 2O 5 30wt%,Na 2 O18wt%.
