then the that is used to complete the process (P4O6 + 2O2 --> P4O10). (See also this page). Also, this page mentions the enthalpy involved; both are exothermic, but the first gives off less energy. Possibly this is why it happens in preference to the second (but I...
The continued development of ferroelectric materials into more and more consumer led applications has been at the forefront of recent ferroelectric material research. It is, however, possible to view a ferroelectric as a wide band gap semi-conductor that can sustain a surface charge density. This ...
