The results show that the material has good antibiotic and safety properties, the acute toxicity taken by stomata is LD 50 >8000mg/kg （little and big white rats）, and the normal quantity in subacute toxicity test is 80mg/（kg·d）. The better mass fraction of doping Ag2O in antibiotic material carried by Al2O3 is 4%CD*28%, and the optimal sintering temperature is from 1000℃ to 1100℃.展开更多
文摘The preparation technique and properties of Ag-type inorganic antibiotic material carried by Al2O3 were studied. The results show that the material has good antibiotic and safety properties, the acute toxicity taken by stomata is LD 50 >8000mg/kg （little and big white rats）, and the normal quantity in subacute toxicity test is 80mg/（kg·d）. The better mass fraction of doping Ag2O in antibiotic material carried by Al2O3 is 4%CD*28%, and the optimal sintering temperature is from 1000℃ to 1100℃.
