Yttrium barium copper oxide is a chemical compound containing the four elements in its name. It is represented by the general molecular formula YBa2Cu3O7-x, according to American Elements. It is sometimes abbreviated as YBCO, explains Chemistry World. Its superconductive properties are used industrially in relation to magnets.
A molecule of yttrium barium copper oxide contains one atom of the element yttrium, two atoms of barium, three atoms of copper and seven atoms of oxygen, all bonded together to form a black, solid crystalline structure. YBCO has a molar mass of about 666.19 grams per mole and a density of 6.3 grams per cubic centimeter. It can be produced through a reaction of yttrium, barium and copper carbonates with oxygen.
