摘　　要：将天然麦饭石与Al2O3、MgO、Ti O2、ZrO2进行混合烧结,通过XRD、IR、红外热效应、红外辐射检测等测试,结果表明,Al2O3-MgO-Ti O2-ZrO2系远红外材料在麦饭石的加入后烧结,有堇青石的生成,所显示的衍射峰分别对应于六方结构堇青石的(112)、(202)、(211)特征峰,(100)晶面衍射峰为堇青石的最强峰;所制基元材料红外热效应明显,A7、MA7 10min的温升分别能够达48.2、51.3℃;红外辐射率分别为0.83、0.86。将制备的远红外基元材料加入到涂料中,涂料红外发射率为0.85。In this thesis,natural medical stone was mix-sintered with Al_2O_3,MgO,TiO2,ZrO2 and through these test,such as XRD,IR,ultra-red ray effect,infrared radiation detection,the result shows：Al_2O_3-MgO-TiO2-ZrO2 were sintered after adding medical stone into far infrared material,and cordierite was formed,the diffraction peak which shows corresponds to the cordierite hexagonal structure,（110） diffraction peak of crystal face is the strongest peak of cordierite;the ultra-red ray effect of make element material obvious,exotherm of A7,MA7 10min can reach to 48.2,51.3℃ separately;the ratioin of infrared radiation is 0.83,0.86 separately.Adding made-up infrared element material into coating,the infrared remittance of coating is 0.85.
