Min, the Apple Watch used Alumina + Zirconia for heat xfer. Aluminum Nitride can also be doped for best heat coefficients

I guess then the major hurdle would be mass sintering Alumina + Zirconia w/ Aluminum Nitride doping in phone sizes...

Min, this is what one of the patents portend to. It is also exampled in the production of the Apple Watch Edition S2.

so the remaining hurdle would be production cost reduction ... ceramic watch ($1249) => aluminum watch ($369)...
