Why was the discovery of high temperature superconductors so startling to scientist?
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 scientists?

What makes a material a superconductor?
There is really no complete theory of superconduction yet. It is believed that in certain materials - the "classical" superconductors - the current is transported by Cooper pairs (i.e., pairs of electrons). However, the classical theory doesn't really explain superconduction in the more recently discovered high-temperature superconductors.
What factors affect the resistance of material to the flow of energy?
The resistivity of metals increases with temperature. Going the other way, some metals become superconductors if the temperature is lowered to a sufficiently low temperature.
Which has the lowest resistance semiconductors superconductors insulator conductor?
superconductors, they have no resistance.
What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
What are properties of a superconductors what they are?
A normal conductor has resistance. A superconductor has no resistance. But to make superconductors a very low temperature is required. High-temperature supeconductors require a temperature of minus 203 degrees C, ordinary superconductors require substantially lower temperatures.
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
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 Superconductivity arises in high temperature superconductors?
I think so the super conducting material used will melt

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
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)
