Superconductor examples

As of 2021, the superconductor with the highest transition temperature at ambient pressure is the cuprate of mercury, barium, and calcium, at around 133 K.

What are the most common superconductors?

The most common engineering superconductors are Nb3Sn and Nb-Ti. They are both metallic so they are malleable, have high critical currents and high critical field densities.

Is mercury is a superconductor?

Although mercury was later found to be a “conventional” superconductor, no microscopic theory so far managed to fully explain the metal's behavior and to predict its critical temperature TC.

Is aluminium a superconductor?

Element	Aluminum
Symbol	Al
Tc (K)	1.2
Tc (°C)	-271.95
Tc (°F)	-457.51

Is Diamond a superconductor?

Electrical resistivity, magnetic susceptibility, specific heat and field-dependent resistance measurements show that boron-doped diamond is a bulk, type-II superconductor below the superconducting transition temperature T(c) approximately 4 K; superconductivity survives in a magnetic field up to Hc2(0) > or = 3.5 T.

Is ice a superconductor?

We show that for realistic levels of doping of a few percent, the phase X of ice becomes superconducting with a critical temperature of about 60 K at 150 GPa. In view of the vast number of hydrides that are strongly covalent bonded, but that remain insulating until rather large pressures.

What is the largest superconductor in the world?

The Large Hadron Collider (LHC) is quite simply the biggest application of superconductivity in the world, with 23 kilometres of superconducting magnets around its 27-kilometre circumference. The phenomenon of superconductivity was discovered in 1911.

What are 2 superconductors?

While most elemental superconductors are type-I, niobium, vanadium, and technetium are elemental type-II superconductors. Boron-doped diamond and silicon are also type-II superconductors.

Which metal is superconductor?

But at very low temperature, some metals acquire zero electrical resistance and zero magnetic induction, the property known as superconductivity. Some of the important superconducting elements are- Aluminium, Zinc, Cadmium, Mercury, and Lead.

Is water a conductor or superconductor?

Pure water is a conductor of electricity.

Is gold a superconductor?

Gold itself does not become a superconductor - above the millidegree range even if it is extremely pure, while none of the gold-rich solid solutions so far studied have proved to be superconducting.

Is diode a superconductor?

Usually, diodes are made out of semiconducting materials forming p–n junctions, which can be used to realize various electronic functionalities, such as rectifiers and photodetectors. Now, Teruo Ono and coworkers report a magnetically controllable superconducting diode that has zero resistance in only one direction.

Is rubber a superconductor?

Insulators, such as rubber or wood, hold on to their electrons tightly and will not allow an electrical current to flow.

Is oxygen a superconductor?

Previous structural experiments1 show that solid oxygen above 96 GPa remains in the molecular state. We conclude therefore that superconductivity of oxygen appears at the molecular metallic state.

Why is gold not a superconductor?

Copper and gold have too much ordinary nonsuperconducting electrons and too big conductivity in normal state. The gain in free energy from superconducting electrons cant compensate antigain from nonsuperconducting electrons and antigain of electron conductivity (hall constant <0).

Can water become superconductor?

Superconductivity at the boiling temperature of water is possible, say physicists. Under pressure: calculated structure of lithium magnesium hydride.

Is MRI a superconductor?

Magnetic Resonance Imaging (MRI), a powerful medical diagnostic tool, is the largest commercial application of superconductivity. The superconducting magnet is the largest and most expensive component of an MRI system.

Can you touch a superconductor?

If I hold it, will I get a shock? Forget for a minute that the superconducting wire will be too cold to touch.

Are humans superconductors?

No, the human body is definitely not a superconductor. A superconductor is a material that looses all resistance below a certain critical temperature. I assure you that at all temperatures the human body has a finite resistance.

Is silicone a superconductor?

Silicon -- the archetypal semiconductor -- has at long last been shown to demonstrate superconductivity. By substituting 9% of the silicon atoms with boron atoms, physicists in France have found that the resistance of the material drops sharply when cooled below 0.35 K (Nature 444 465).
