The requirements for superconductivity Which properties are sufficient evidence for a material to be not superconducting?
I am looking for a set of statements like

If the material is semiconducting, it is not superconducting

Edit: 
I am not looking for a definition of superconductivity, or for introductional literature like the famous W. Buckel. 
I am looking for properties, that would forbid superconductivity. If you have a source for it i would be very glad. As far I remember magnetic atoms will forbid superconductivity too, but i could not find a source yet.
 A: This question has a semi-canonical answer; Matthias' rules for superconductivity. This was a real set of empirical criteria proposed well before the cuprates were discovered, but here is the tongue-in-cheek version (I'm not sure who to attribute this presentation to, however -- comments appreciated).


*

*Symmetric lattices (i.e. cubic),

*Avoid oxygen,

*Avoid magnetism,

*Avoid insulators,

*Avoid theorists ;)


Obviously the cuprates are a knock against all of those, except the bit about theorists. But this should serve as a warning. There are some aspects of superconductivity that are very well understood, but trying to predict its presence or absence in a given material is not a productive activity.
A: Unfortunately, there is no hard and fast set of rules for superconductivity yet. The elemental superconductors and several of the metallic alloys seem to follow a set of rules whereas the high Tc cuprate compounds follow a different set of rules. The latest family of superconductors namely the Oxy-Iron- Pnictides/Chalcogenides meet an altogether different set of conditions.
1) Most metals and metallic alloys - BCS theory, Cooper Pairing, Electron-Phonon interaction, No coexistence of magnetism with superconductivity, obey Tc < 30 K rule. Mostly s-wave pairing symmetry of cooper pair wave function.
2) High Tc Cuprates - No to BCS theory, possibly cooper pairing, may not have electron-phonon coupling, etc. Tc > 30 K to 165 K. 30 K barrier broken. Competing orders of magnetism and superconductivity. d-wave or related pairing symmetry. No theory yet.
3) Iron Pnictides/ Chalcogenides - Co-existence of competing orders of magnetism and superconductivity, different pairing symmetry when compared with conventional and cuprate superconductors, possibly p-wave pairing. Tc's span from very low temperatures to around 60 K within 7 years of discovery. Tc's poised to increase. May provide crucial understanding towards high Tc mechanism of superconductivity. No theory yet.
So, there seems to be no hard and fast rules set yet.
A: I doubt that any such statement exists, as it would imply a very deep understanding of superconductivity we don’t currently have.
This holds especially as you apparently look for temperature-independent statements, whereas most metals can be made superconducting at sufficiently low temperatures, and all high-temperature (relatively, still a few hundred degrees below $0^\circ\textrm{C}$) superconductors are made of materials that are very bad conductors at higher temperatures (ceramics and the like). The converse that all ceramics are good superconductors is not true, either.
A: A material is superconducting if the electrons in the electric current form "bosonic" cooper pairs.
A material is not superconducting if the current is formed of hadrons which interact with conductor.
I'm not an expert by any stretch of the imagination. Infact less than a beginner on the subject.
Introduction to Solid State Physics by C. Kittel has a basic chapter on superconductivity.
A: Here are two (equivalent) definitions of superconductivity:


*

*A material is superconducting, if it shows the Meissner effect.

*A material is superconducting, if a ring exhibits a persistent current when threaded by a magnetic field which is independent on the size of the ring.
Note that both definitions are via magnetic properties and not the fact that the resistance vanishes!
