Konduktivitas panas uranium dioksida tergolong rendah bila dibandingkan dengan metal zirconium, dan terus terus menurun seiring dengan naiknya suhu.
The thermal conductivity of uranium dioxide is very low compaired with that of zirconium metal, and it goes down as the temperture goes up.

It is important to note that the corrosion of uranium dioxide in an [[aqueous]] environment is controlled by similar [[electrochemical]] processes to the [[galvanic]] [[corrosion]] of a metal surface.
