载银Al_2O_3抗菌剂的制备及性能研究

Preparing and antibiotic property of Al_2O_3 doped-Ag

报导了采用Al2O3为载体的银型无机抗菌材料的制备工艺及性能,所制备的无机抗菌材料具有良好的抗菌性能及安全性能,其中对大、小白鼠的急性经口毒性的LD50>5000mg/kg,亚急性毒性试验的无异常、无作用的量为100mg/kg·d;Ag2O的较佳掺入量为3wt%-5wt%,较佳的烧结温度范围为1000-1200℃。

The preparing technology and properties of Ag-type inorganic antibiotic material carried by Al2O3 were studied. The material has good antibiotic and safety property, the acute toxicity taken by stomata is LD50 > 5000 mg/kg to little and big white rats, and the normal quantity in subacute toxicity test is 100 mg/kg·d. The better quantity of Ag2O in the antibiotic material carried by Al2O3 is 3 wt% 5 wt% and the better sintering temperature range is 1000-1200°C.
