Equipment
To make an yttrium-barium-copper-oxide superconductor, you will need:
* Yttrium Oxide
* Barium Carbonate (TOXIC)
* Cupric Oxide
* A Laboratory Furnace or a converted pottery kiln.
* Labware made of alumina.
* An Oxygen Source
* Liquid Nitrogen and a rare-earth magnet for testing and demonstrating the superconductors.
Method
There are a number of methods of producing ceramic superconductors like this, but the simplest is the so-called "shake and bake" method, which involves a four step process:
1. Mixing the chemicals;
2. Calcination(the initial firing);
3. The intermediate firing(s) (oxygen annealings);
4. The final oxygen annealing.

A material that has almost zero resistance when it is cooled to low temperatures is a....?
Super Conductor :)
What is a super conductor and what are some of its uses?
A super conductor is a material which when cooled to a low enough temperature, will exhibit an electrical resistance of zero. Uses include building very powerful electromagnets and Josephson junctions for scanning microscopes.
Who invented super conductor?
The property of superconductivity was discovered by Heike Kamerlingh Onnes, in Leiden, South Holland, in 1911.
When cooled this contains almost zero resistance?
Anything with the property of zero electrical resistance is called a super-conductor.
How is Mercury a superconductors?
mercury is not a superconductor. However at a certain temperature is is known to have a super low resistance meaning that electricity could move much quicker ,making it a super conductor
Is brass a super conductor of electricity?
brass is a good conductor, not a super conductor.
What is the difference between super conductor and perfect conductor?
A perfect conductor will have absolutely no losses. A super conductor will be essentially lossless if it can be kept at a specific temperature. As it deviates from this temperature, its' losses will increase.
What is the name of a low resistance conductor in electrical engineering?
super conductor
How can you make electricity flow?
Use a good conductor - if possible a super conductor.
Is chrome metal super electric conductor?
YES IT IS! But there ARE types of plating out there that are non conductive just do a search on google to find it... easy as pie..
How can you make electricity flow effiectively?
Use a good conductor - if possible a super conductor.
Can you apply magnetic field on super conductor?
Yes. One application of a magnetic field on a super conductor is quantum locking. Imagine the field lined of magnet penetrating an object. Now transform that object into a super conductor (i.e. super cool a substance that is not a super conductor at room temp into a super conductor by cooling it to a point where it is). That object is now quantum locked on the field lines and will tend to remain in a similar position without outside influence, besides the magnet, of course. It is such a principle that mag-lev trains that use superconductors operate on.
How much does a super conductor tyranno cost?
it depends where you get it
What is special about a super conductor?
Conducts electric currents without resistence (loss). That's super.
How do some metals become super conductors?
Some metals become a super conductor when you freeze them
Why super conductor is not used?
b'coz super conductivity is achieved only when the material is cooled below a critical temperature. if it cooled above the critical temp. than the material ceases to be a super conductor. to maintain it conductivity helium and liquid nitrogen which is not easy 2 be used that is why super conductor can't be used for commercial purposes in our day to day life
Is there any real super conductors?
Yes,Mercury at 4kelvin is a super conductor it can be cooled down to that temperature.
