| Antibacterial materials had become newly functional materials with great social and economic importance.In the first chapter,several basic issues including the harmful effect about microorganism,conception of antibacterial,antibacterial agents,antibacterial mechanism of inorganic antibacterial materials,application of inorganic antibacterial agents,preparation methods of antibacterial agents,and progress of antibacterial materials.Ag2Mo2O7,ZnMoO4 and CoMoO4 were synthesized via the solid-state reaction, co-precipitation,and hydrothermal synthesis.The molybdate were confirmed by X-ray diffraction and X-ray photoelectron spectroscopy.Antibacterial test were taken to compare the antibacterial activity with phosphates.The antibacterial activity of molybdates is better than that of phosphates.Contrapose to resisting high temperature antibacterial materials is inadequate now, silver-carrying zirconium phosphate agent which can resist high temperature was prepared. Zr(HPO4)2·H2O has ion exchanging function.The researched synthesization methods need long time and gained a little once a time yet.A mass of Zr(HPO4)2·H2O was prepared by co-precipitation.After the ion exchanging with Ag+,the obtained silver-carrying zirconium phosphate antibacterial agent was heat-treated at different temperatures.AgZr2(PO4)3 was obtained after heat-treating at 1100℃and it existed after heat-treating at 1350℃.So the antibacterial agent kept nice antibacterial performance from room temperature to 1350℃. Antibacterial ceramics were then prepared with the silver-carrying zirconium phosphate, and calcined at 1350℃.The antibacterial effectiveness was evaluated against E.coli.The results indicated that the bactericidal rate of antibacterial ceramics with antibacterial agent of 7wt%can be reach 99.6%.There is an advantage of low cost antibacterial chinaware.The decreasing cost antibacterial performances for Chinaware about the Second Glazing and Imitating Decoration of Chinaware were developed.Silver-carryingγ-alumina and glaze were used in the Second Glazing technology.Silver-carryingγ-alumina was mixed with ceramic glaze,then spreaded onto chinawares and heat-treated at 1050℃for 15min. Antibacrerial chinawares were gained.Antibacterial rate test indicated that the bactericidal rate of antibacterial chinaware with the silver-carryingγ-alumina agent of 2.5wt% Can be reached 99.97%.Silver-carrying nano-hydroxyapatite and flux were used in the other technology.Silver-carrying nano-hydroxyapatite was mixed with flux,and then distilled water and CMC were added in.After mixing around the mixure.spreaded it onto the chinawares.At last they were heat-treated at 800℃for 20min.The technology can be operated with decorating the chinawares.The bactericidal rate of antibacterial ceramics with antibacterial agent of 9wt%in the solution of flux can be reached 98.5%.And in this technology slight deflection of heat- treating temperature and heat preservation time effect the antibacterial rate tiny.Also research ameliorating the surface of antibacterial chinawares.
