摘      要：In order to enhance the sintering resistance of lanthanum aluminate based high emissivity coatings,Ca^(2+)-Fe^(3+)doped LaAlO_(3)/ZrO_(2)specimens were prepared by solid state sintering using La_(2)O_(3),Al_(2)O_(3),CaCO_(3) and Fe_(2)O_(3) as raw materials,extra-adding fused Y_(2)O_(3)-stabilized ZrO_(2)(0,5%,10%,and 15%,by mass),ball milling,pre-calcining,pressing into shapes and sintering at 1600℃for 2 *** effect of the ZrO_(2)addition on the properties of lanthanum aluminate based high emissivity coatings was *** is concluded that ZrO_(2)does not react with LaAlO_(3),which can inhibit the sintering of the *** the increase of the ZrO_(2),addition,the linear shrinkage rate and the thermal conductivity decrease significantly,while the emissivity decreases,but the emissivity of all the specimens is all higher than *** optimal addition of ZrO_(2),is 10%.
