Abstract: A series of inorganic antibacterial materials with strong antibacterial function and high safety , including the materials which can resist high temperature (1350℃ ), were obtained by studying their carriers, antibacterial metallic ions and preparing techniques. The experiment results show that the minimum bacteriostatic consistency is MIC ≤ 75 ppm (Escherichia coli and staphylococcus), the acute toxicity taken orally is LD>10000mg/kg (little and big white rats), the normal quantity in subacute toxicity test is 100mg/kg·d.

Key words: inorganic antibacterial material, antibacterial property, safety property
