研究了近零热膨胀ZrW2O8/ZrO2和添加Al2O3的ZrW2O8/ZrO2复合材料的微观结构、导热性能和导电性能。两种复合材料的导热系数都很低，随着温度的升高，导热系数略有下降。两种复合材料的电导率随测量温度的升高而增大。添加Al2O3的ZrW2O8/ZrO2复合材料的导热性和导电性均高于ZrW2O8/ZrO2复合材料。造成复合材料导热性和导电性差异的最重要因素是孔隙率。(C) 2008日本陶瓷学会。版权所有。
In this work, the microstructure, thermal and electric conductivity properties of near-zero thermal expansion ZrW2O8/ZrO2 and Al2O3 added ZrW2O8/ZrO2 composites were studied. Both the two composites exhibit very low thermal conductivity and the thermal conductivity decreases slightly as the temperature increases. The electric conductivity of the two composites increases with the increasing of the measurement temperature. The Al2O3 added ZrW2O8/ZrO2 composite has higher thermal and electric conductivity than ZrW2O8/ZrO2 composite. The most important factor which causes the difference of the thermal and electric conductivity of the composites is the porosity. (C) 2008 The Ceramic Society of Japan. All rights reserved.
