| Abstract: | 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>8 000 mg/kg (little and big white rats), and the normal quantity in subacute toxicity test is 80 mg/(kg · d). The better
mass fraction of doping Ag2O in antibiotic material carried by Al2O3 is 4%–8%, and the optimal sintering temperature is from 1 000 °C to 1 100 °C.
