Ok, so when I go down to the beach I see lots of rocks and pebbles. Today I found coal and some charcoal from the pier that burned a few months ago. So I was wondering if I can find flint or quartz there for my (material) n steel lighter? I have steel, tinder, wood and coal, now that's the only thing left. So can I find flint or quartz there, or where? Where did you find them? Anything help is appreciated.
Your question is very interesting. There are many websites that are similarly interesting. However, naturally found was not easy to decipher. There is barium titanate, a typical ferroelectric of the displacive type, is due to a polarization catastrophe, in which, if an ion is displaced from equilibrium slightly, the force from the local electric fields due to the ions in the crystal increase faster than the elastic-restoring forces. This leads to an asymmetrical shift in the equilibrium ion positions and hence to a permanent dipole moment. In an order-disorder ferroelectric, there is a dipole moment in each unit cell, but at high temperatures they are pointing in random directions. Upon lowering the temperature and going through the phase transition, the dipoles order, all pointing in the same direction within a domain. The other one is lead zirconate titanate.
Regular quartz crystals have to be cut accurately in the x,y an z planes to resonate properly. If somebody made a dog's breakfast of the cutting process then inserting an MM between two pieces of wire would be more accurate.
