Not likely. Those materials are far too expensive, too brittle when dropped (even though they have great scratch resistance), they trap heat, they greatly attenuate radio signals, not easy to make into the curved shapes of a smartphone housing, etc.This leaves the door open for the use of novel materials such as ceramic or sapphire as opposed to the metals now used, I wonder if these alternatives have been looked at by Apple?
