Materials that will form superconductors come in two basic varieties, those which are metals or alloys of metals and the newer variety that are ceramic-like materials.
Some examples in the metal category are are Mercury, Niobium, Tin, Lead and various alloys and the second category includes the more complex compounds Lanthanum-Barium-Copper Oxide and Yttrium-Barium-Copper Oxide.
The first category are the outgrowth from the original discovery of superconductivity in 1911 and are now referred to as low temperature superconductors. The 1986 discovery of a new class of compounds called high temperature superconductors gave rise to the second category. The first category has materials that are limited to about 30 degrees Kelvin above absolute zero. The second includes materials that can remain superconducting up to about 130 K.

What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
What types of materials are Porous?
Sedimentary rocks such as sandstone are examples of porous materials.
What are three main uses of helium?
cooling superconductors
Examples of homogeneous materials?
metals , plastics , glass and ceramic
Which material produces heat energy when current is passed through them?
Actually, ALL materials do ... at least, all materials that you're ever going to see outside of a laboratory or a stripped down MRI machine. The only exceptions are the so-called "superconductors", which have zero resistance and don't dissipate any electrical energy.
What do you call materials with the resistance of ohms?
superconductors
What materials don't have any resistance?
superconductors
How are superconductors different from insulators?
Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
What are materials that have infinite conductivity at low temperatures?
superconductors
What do you call materials with a resistance of 0 W?
superconductors
How do superconductors conduct electricity?
Superconductivity is where there's absolutely zero electrical resistance or magnetic expulsion. Materials that are superconductors conduct electricity much like other materials, but more efficiently.
What type of materials allows electricity to flow through them unimpeded?
Superconductors
What is the term for the materials that have very low thermal energy resistance?
superconductors
Certain materials can become superconductors unedr what conditions?
Very low temperatures.
What is the term for materials that have very low thermal and energy resistance?
superconductors
What has the author Benjamin Washington Roberts written?
Benjamin Washington Roberts has written: 'Superconductive materials and some of their properties' -- subject(s): Superconductors 'Properties of selected superconductive materials, 1978 supplement' -- subject(s): Superconductors
Is a superconductor a metal or nonmetal?
Only a few of the materials that have been supercooled have become superconductors, and not all of those are metals. There have even been some organic superconductors discovered.
