High temperature superconductors are materials that can conduct electricity without any resistance at relatively higher temperatures compared to conventional superconductors. They exhibit this property at temperatures above -180 degrees Celsius, making them more practical for various applications such as MRI machines and power grids. These materials have unique crystal structures that allow for the flow of electrons without dissipating energy as heat.

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.
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.
Why was the discovery of high temperature superconductors so startling to scientist?
The discovery of high temperature superconductors was startling to scientists because it defied previous understanding of superconductivity, which was thought to only occur at very low temperatures. These new materials exhibited superconducting properties at relatively higher temperatures, opening up new possibilities for practical applications.
What is the lowest temp that super conductors will work?
Superconductors typically work at extremely low temperatures, with the critical temperature being the point at which they transition to a superconducting state. Conventional superconductors require temperatures close to absolute zero (around -273 degrees Celsius or 0 Kelvin), while high-temperature superconductors can operate at higher, but still very low, temperatures around -135 degrees Celsius.
Which has the lowest resistance semiconductors superconductors insulator conductor?
Superconductors have the lowest resistance of all materials, with resistance dropping to zero when they are cooled below a certain critical temperature. Conductors have lower resistance than semiconductors and insulators, which have significantly higher resistance and do not conduct electricity as effectively.
What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
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.

What has the author Hong Alice Wang written?
Hong Alice Wang has written: 'Reactions during processing of the 123 high Tc superconductor' -- subject(s): Ceramic superconductors, 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.
How do you make room temperature superconductors inductor?
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.
How do you make room temperature superconductors inductor coil?

Can you name some superconductors having high critical temperature?
some superconductors having high critical temperature :YBa2Cu3O7 have Tc=93 K (1987)BiSr2CaCu2O8+x Tc=94 K (1988)Ta2Ba2Ca2Cu3O10+x Tc=125 K (1988)HGBa2Ca2Cu3O8+x Tc=150 K (1993)
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.
Why are scientists trying to make superconductors that can work at warmer temperatures?
Because refrigerating superconductors to the cryogenic temperatures needed by current ones is expensive, severely limiting the applications they are used in.Metallic superconductors need cooling to the temperature of liquid helium.Copper oxide ceramic superconductors need cooling to the temperature of liquid nitrogen.Room temperature superconductors, if they exist, would need little or no cooling.
What is a material that has no electrical resistance?
The class of materials called superconductors have no DC resistance when cooled below their transition temperature. This temperature varies with the material and is below 20K for metallic superconductors and generally below about 100K for oxide or "High Temperature" superconductors
