Properties and preparing of Ag-type antibiotic materials carried by oxide

The preparing technology and properties of Ag-type inorganic antibiotic materials carried by SiO_2,CaO,Al_2O_3 were studied. The test results indicate: the materials have favourable antibiotic property and MIC≤7.5×10~(-5) (escherichia coli and staphylococcus); at the safety, the acute toxicity taken by stomata was LD_(50)10000mg/kg (little and big white rats), the normal quantity in subacute toxicity test was 100mg/kg·d. The better quantity of doped-Ag in antibiotic material carried by CaO was 4%～8% and the better sintering temperature range was 1000～1200℃.
