Dear Sirs:
I am working on a heat transfer model for hollow alumina spheres for high temperature aplications, but I have had a difficult time finding the thermal properties of alumina (Al2O3, 94-95% purity). In particular its thermal conductivity for a wide range of temperatures (300 K up to 2,000 K). It would be of great help if you could point me out to technical handbooks or specific research papers with empirical or even theoretical information for this property.
Thanks in advance for your support.
Best Regards.
Nicolás Ripoll

Extrapolate down to 300K if needs be.
Might be a better dataset referenced in that work.
Dear James:
Kudos on your increadibly speedy reply. It was spot on!
Best regards.

Dear, Nicolas A.
Heat transfer by Holman or any textbook of heat transfer.
Dear Najeeb:
Thanks for your reply, but normal heat transfer textbooks don't have information on the thermal conductivity of ceramics (such as alumina, Al2O3) as a function of temperature for a wide range of temperatures (300 K to 2,000 K, in my case). However, thanks to the paper pointed out above by James I was able to discover the Defense Technical Information Center for USA (https://discover.dtic.mil/), which has open access technical reports on the thermophysical properties of matter on a wide range of temperature.
I hope this helps anyone with the same question that I had.
Sincerely,
Nicolás Ripoll
Nicolás,
Give the NASA Technical Report Server a try too - a wide variety of exotic materials will have been examined for aerospace use too.
