What are four potential uses for high-temperature super conducting materials?
826765
High-temperature super conducting materials are ideal for any application that requires heat transfer such as cookware, clothing irons, welding, fire rescue equipment.

good conductor of heat and electricity, a metal, lustre, maleable and ductile...

good conductors are material with very tight atomic structure. Remember you are talking about electron flow here. they flow best and easies through material with very tight atomic make up like lead gold copper aluminum silver so forth. Most good conductors are non ferrous metals. This means If you heat them up to melting point they will not get red hot first, you will see very little color change in them from solid to liquid state.

Its a Metal, hence responds to / is a conductor of heat.\n\nIts fluid so the expansion per gradient of heat would be highest.\n\n\nAll other liquids are not a conductor of heat ( or as good as mercury)

Umm,.. hmm.  You should probably google this, keyword: superconductors.  Its not really a new discovery.

Superconductors are a reality. A superconductor is a conductor that will conduct electricity without resistance below a certain temperature, decreasing the amount of energy lost during current flow. The theory is that if a metal with no resistance to current flow is used, the current will continue to flow in a continuous loop. This has yet to happen because of thermodynamic restrictions, but superconductors of very high efficiency are currently in use in MRI machines and trains.\n\nCheck out the website for more info. It's really interesting stuff.

Semiconductors are used all over the place, as others mentioned. \n\nSuperconductors have a number of applications, too, but their need for extreme cooling in order to operate limits their use. \n\nSome currently used applications for superconductors:\n\nSMES systems (Superconducting Magnetic Energy Storage) used in the power grid and at certain high power raw facilities. \n\nMagnets for MRI systems.  Superconductors make for fantastic electromagnets since the current moves through the coil without resistance\n \nElectromagnets in particle accelerators.  All modern particle accelerator facilities use superconducting magnets.\n\nHTSC SQUIDs.  These are "high T-sub-c Superconducting Quantum Interference Devices" which are a very sensitive sort of electromagnetic sensor based on a Josephson junction device.  These are used by the military, specifically the navy, to sense mines and submarines by the electromagnetic disturbance a large piece of metal makes in seawater. HTSC SQUIDs also have brain sensor applications and may someday result in technology that makes it possible to very accurately observe human brain activity with an easily transportable device.\n\nSuperconducting generators.  Just as superconductors make for excellent electromagnets, they also make great electrical generators.  The use of them is limited, but demand is growing.\n\nUltra high power electric motors.  Although not in widespread use, superconductors can be used to make very powerful electric motors.  The record so far is a 5000 horsepower motor.    \n\nRapid discharge of a SMES has also been used to make an "e-bomb".  This is an EMP (electromagnetic pulse) type weapon that can disable electronics and communication devices.  SMES make a perfect basis for EMP generation because of the huge energy density and rapid discharge.  The first field use of a SMES based e-bomb was in Iraq in 2003.

Simply put, it's not a conductor. \n\nhttp://jchemed.chem.wisc.edu/JCEsoft/CCA/CCA1/MVHTM/R0540/S567.HTM

I think it's these metals chrome, cobalt, titanium, or ceramic materials can be used.  I think they have recalled ceramic because they were cracking though.

errr, grind metals to a fine powder and mix them together and press them and you can get alloys physically impossible to make by forging.\n\numm, grind metal very fine so the oxidise and use them to make metal fires, such as "thermalite" for welding traintracks.

Depends on the application you have for the copper. You can shield it from oxygen and other corrosive agents using a protective atmosphere.\n\nAt 500°C exposed to atmospheric oxygen you will want a solid metal with a stable passivizing surface or too noble to react. Titanium or platinum will probably be overkill, stainless steel may discolour.\n\nOr you might be thinking about a sacrificial anode, leaving the copper intact but dissolving the connected material (e.g. zinc or magnesium).

Four things I'm waiting for, and hope to see in my lifetime:\n\nAn inexpensively-made material that is superconducting at "normal" temperatures.\n\nPractical fusion power. (Though that would probably follow naturally from the first one.)\n\nSome cheap way to break down any substance into its elemental components.  Everything would then be recyclable.\n\nCheap manufacturing of carbon nanomaterials such as hyperfilament, "Bucky tubes" and the like.\n\nIf you can get any of these ideas to work, you're welcome to steal them.\n\n-- Oh, and an anti-microwave; something that freezes as fast as a microwave cooks.

They are used to prevent cracking and tearing of various types of materials due to expansion and contraction of said materials because of temperature changes. What else do you need to know?

The hotter the surface gets the more resistance. It is a solid state item.

it gets hot, which in turn causes more resistance, and it gets even hotter, which causes more resistance.  if there are enough amps, the metal will melt.

Superconductors are electrical conductors which have a very low resistance.  In the past these materials need to be at very low temperatures.  Recent advances have allowed the creation of HTS (high temperature superconductors) which can operate at very much higher tempteratures than before.

High temperatures, limit or exclude oxygen.
