The main class of high-temperature superconductors are in the class of copper oxides (only some particular copper oxides) especially the Rare-earth barium copper oxides (REBCOs) such as Yttrium barium copper oxide (YBCO).
<h3>What superconducting material works with the highest temperature?</h3>
As of 2020, the material with the highest accepted superconducting temperature is an extremely pressurized carbonaceous sulfur hydride with a critical transition temperature of +15°C at 267 GPa.
<h3>How do high-temperature superconductors work?</h3>
High-temperature superconductivity, the ability of certain materials to conduct electricity with zero electrical resistance at temperatures above the boiling point of liquid nitrogen, was unexpectedly discovered in copper oxide (cuprate) materials in 1987.

Aluminum sulfide is Al₂S₃, which shows that there are 3
sulfur atoms per formula unit.
In one mole there is Avogadro’s number of atoms and Avogadro’s
number = 6.02 x 10²³
In 1.10 mole = 1.10 x 6.02x10²³ = 6.62 x 10²³ formula units
Now multiply with 3 to get number of sulfur atoms present in
1.10 mol of Aluminum sulfide;
3 x 6.62x10²³ = 1.99 x 10²⁴
So, the answer is 1.99 x 10²⁴ sulfur atoms.
