Abstract: The far -infrared dialy -used ceramics not only has effect of activation on food, drink, water and accelerating wine fermentation,but also has the function of health care on body .Liquid phase method is adopted to prepare nanometer far -infrared radiating ceramic powders in this study, which can make into high -effect far -infrared radiating properties daily -used ceramic products at normal temperature, such as bowl, plate, dish, cup,wine utensils, etc when added it into general ceramic glaze in the light of propriety proportion .Phase composition is analyzed by XRD and microstructure is observed by SEM .The results show that the glossiness and microhardness of the dialy -used ceramic glaze are improved, and the quality of glaze surface is of high quality when the addition quntity of far -infrared ceramic powders is 10wt %.After the installed test by China Meterage Research Institute, the emissivity of far -infrared ceramic powders achieves 94 % and the emissivity of far -infrared ceramic glaze achieves above 83 % at normal temperature .

Keywords: far -infrared ceramic powders, glaze, dialy -used ceramics .
