常温远红外陶瓷粉和远红外日用陶瓷的研究

远红外日用陶瓷不仅对食物、饲料、水有活化作用，加速酒的发酵和成熟，而且对人体还具有保健功能。本研究采用液相法制备出纳米远红外陶瓷粉，把远红外陶瓷粉按适当比例掺入普通陶瓷釉浆中，制成常温下具有高效发射锭红外线功能的日用陶瓷产品。如瓷碗、盘、茶杯、酒具等。脸用XRD分析其物相和SEM观察其显微结构、结果表明，当远红外陶瓷粉在基釉中的添加量为10wt％时，可提高日用陶瓷釉面的光泽度和显微硬度，且釉面质量优良。经中国计量科学研究院测试，远红外陶瓷粉的法向全辐射发射率94％，远红外日用陶瓷的法向全辐射发射率达到83％以上。

STUDY ON NORMAL TEMPERATURE FAR-INFRARED CERAMIC POWDERS AND DIALY-USED CERAMICS

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 quantity 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.
