Hot Superconductor, Cold Superconductor

This is impossible, BaTiO3,

vboom=3.4354602056+22+83=202.76ms1

Tboom=202.762233.19210328.3144=576.50K  or 303.35oC

This is way hot.  Temperature is know to decrease conductivity.  An impossible hot superconductor.

For CaCu3Ti4O12,

vboom=3.4354470020+293+224+812=55.49ms1

Tboom=55.492614.178910328.3144=43.17K  or 229.98oC

This is cold.  The cell unit is too big to be considered as a quasi-nucleus.   Maybe it is possible to parcel out molar mass and arrive at a density value for copper only in the crystal structure.

fCu=totalmolarmassCutotalatomicmolarmass

MmCu=MmfCumolarmassCu

where Mm is molecular mass,

ρcu=ρm.fcu

where ρm and ρcu are crystal density and density of Cu in the structure, and so consider only copper in the structure.

So,

fCu=63.5463614.1789=0.310

ρcu=47000.310=1458.86kgm3

Considering only Cu in CaCu3Ti4O12,

vboom=3.43541458.86293=57.60ms1

Tboom=57.60263.546310328.3144=38.03K

It does not seem to work.  Furthermore, to consider collisions with Cu only, the atomic will have to dominate the structure in size.  The rest of the molecules is as if does not exist.  Even so, three separate Cu atoms does not form a quasi-nucleus.  Maybe,

vboom=3.43541458.8629=172.82ms1

Tboom=172.82263.54610328.3144=114.13K

which does not show what to do next.  At best at small hump around 114.13K in a decaying conductivity profile as temperature decreases.

What about copper by itself as a metal;

vboom=3.4354896029=1061.42ms1

Tboom=1061.42263.54610328.3144=4305.29K  or 4032.14oC

which is not indicative of its high conductivity of electricity.  For this reason a folly...
