At room temperature,the thermal conductivity of copper(395 W/mK) is much higher than that of Aluminium (235W/mK). So what is reason behind higher thermal conductivity of aluminium oxide?What structural changes lead to this result?
Hi
I think copper is more corrosive than aluminium, this may be one of the reason

Dear Vipin,
Could you kindly quote the so observed value of thermal conductivity for alumina. I quickly did a search for the thermal conductivity for materials and found that general form of alumina is (relatively) a poor conductor of heat than any form of copper.

Maybe provide a link to the original publication or description of the experimental conditions (and results) so that it may help to address your question.

Do you know the correlation between thermal conductivity of copper oxide and temperature. Similarly, is there any correlation between thermal conductivity of aluminium oxide and temperature?
