Very interesting! But doesn't the article get the thermal properties backwards? Would hurt cooling when heat source inside.

Ceramic shuttle tiles were insulator from the heat outside the shuttle at re-entry. In a phone would stop heat from escaping.

Petrus, great point! The Shuttle tiles used silica ceramics with uniform air pockets. Zirconia will transfer heat away.

As far as I understand Zirconia has extremely low heat conductivity and is thus horrible for hot electronics. Anti-heat-sink.

A hot GPU needs the heat to quickly conduct away and exit the device enclosure. Zirconia would stop heat from conducting away

Petrus, indeed. The new Apple Watch Edition shows the use of Alumina + Zirconia = thermal conduction + other mediations.
