State why some insulatores such "ceramic " can become a superconductor when cooled to a temprature of 0 K.
Well by definition, when certain elements are cooled down to a very low temperature often a few degrees above 0K which is charateristic to that particular element, show a remarkable property that they lose all trace of electrical resistance.

Also, one interesting general property of superconductors is that, materials which are good conductors at ordinary temperatures are not superconductors and superconducting materials are not good conductors at room temperatures.
