What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
How do you make room temperature superconductors inductor coil?
We currently don't know of any room temperature superconductors; we've managed to find some "high temperature" superconductors, but "high" in this case means "liquid nitrogen temperatures" ... about two hundred degrees Celsius below zero. The lowest naturally occurring temperature ever recorded on Earth is about 184K ... about fifty degrees Celsius above the point at which the highest-known-temperature superconductor becomes superconducting.
What are examples of materials that are superconductors?
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.
Does superconductor work in alternating current?
Yes, superconductors can carry alternating current (AC) without resistance, but their behavior differs from that in direct current (DC) applications. The critical frequency of the AC must be below a certain threshold for the superconductor to maintain its properties. However, at higher frequencies, the effects of magnetic fields and other factors can lead to energy losses, making them less effective for high-frequency AC applications. Overall, while superconductors can work with AC, their performance is influenced by frequency and other conditions.
How is temperature affected if there is a high pressure in the atmosphere?
High pressure = High temperature
What is the highest critical temperature of superconductor?
133 Kelvin, about -140 Celsius. This is the critical temperature of a mercury -based superconductor. It contains copper-oxide, a common theme, I believe, in high temperature superconductors
What are properties of a superconductors what they are?
Superconductors are materials that can conduct electricity with zero resistance when cooled below a certain critical temperature. They also exhibit the Meissner effect, which expels magnetic fields from their interior. Superconductors have a critical magnetic field above which they cease to superconduct.
What superconductor works best with higher temperature?
High-temperature superconductors are most commonly based on copper-oxide or iron-based compounds. Among these, yttrium barium copper oxide (YBCO) is one of the most widely studied and used high-temperature superconductors due to its relatively high critical temperature of around 90 K.
What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
Lowest temperature of superconductivity?
The lowest temperature at which superconductivity can occur is called the critical temperature. This temperature varies depending on the material. Some superconductors have critical temperatures close to absolute zero (0 Kelvin), while others have critical temperatures as high as -140 degrees Celsius.

What is the definition of low temperature supercoductors?
In a way, all currently existing superconductors are "low-temperature", but some more so than others. The traditional superconductors work up to about 20 K (or minus 253 Centigrade); more recent "high-temperature superconductors" work up to 100 K or so. 100 K is still minus 173 Centigrade, but it is much "hotter" than the traditional superconductors. The new "high-temperature" superconductors apparently work different than the old-fashioned ones; at least, the theory that explains the traditional superconductors fails to explain how the new superconductors work.

How Superconductivity arises in high temperature superconductors?
I think so the super conducting material used will melt
Why was the discovery of high-temperature superconductors so startling to scientists?
It was startling because it was said to be impossible by the BCS theory.
