[Means for Solving the Problems]
The antibacterial glass of the present invention has a composition in which 10 to 50% by weight of SiO 2 , 10 to 54% by weight of B 2 O 3 , and one of alkali metal oxides (Na 2 O, K 2 O and Li 2 O). or two or more) 0-20 wt%, the Al 2 O 3 0 to 20% by weight, the TiO 2 0 wt%, the La 2 O 3 0 wt% (excluding 10% by weight ) Containing 0.1 to 5.0% by weight of Ag 2 O and 35 to 60% by weight of one or more of ZnO, BaO, CaO and MgO, and having an average particle size of 10 μm. The elution rate of silver is 0.005 to 5.0 mg / g / hr, and the refractive index is 1.57 to 1.63.
La2O3は、抗菌性ガラスの屈折率を高める効果があり添加してもよいが、水中への銀の溶出速度を低下させ、また高価であるため、その添加量は０〜１０％（ただし、１０％を除く）が好ましい。また、La2O3は、ZnO、BaO、CaOおよびMgOと協調して抗菌性ガラスの屈折率を高める。したがって、La2O3の添加量が０〜１０％（ただし、１０％を除く）の場合は、屈折率を目的の範囲内に調整するため、ZnO、BaO、CaOおよびMgOの１種または２種以上を３５〜６０％とする必要がある。 La 2 O 3 has the effect of increasing the refractive index of the antibacterial glass and may be added. However, since the rate of silver elution into water is reduced and it is expensive, the amount of La 2 O 3 added is 0 to 10% ( However, excluding 10%) is preferable. Also, La 2 O 3 increases the refractive index of the antibacterial glass in cooperation with ZnO, BaO, CaO and MgO. Therefore, when the addition amount of La 2 O 3 is 0 to 10% (excluding 10%) , one or two or more of ZnO, BaO, CaO, and MgO are used in order to adjust the refractive index to a target range. It is necessary to make the seed or more 35-60%.
