The theory is the crystal structure induced by oxidation and vibration is responsible for the superconducting effect. They literally dropped and cracked the quartz ampoule by accident and produced the sample. Its not enough to produce the material itself, it seems it is an emergent property of the structure and formation of the material similar to piezoelectric effect?
