03102019 The oxide of yttrium-barium-copper also known as YBCO spoken.
Chemical formula of yttrium barium copper oxide. Yttrium barium copper oxide often abbreviated YBCO is a chemical compound with the formula Y Ba 2 Cu 3 O 7. Beyond 05 it changes into insulating state. It transforms into the hydroxide on contact with water.
Yttrium barium copper oxide and Yttrium. It includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen 77 K at about 90 K. Yttrium barium copper oxide Names IUPAC name.
BaO H2O Ba OH2. Chemical formula is YBa2Cu3O7x. 2Ba O2 2BaO.
Barium copper yttrium oxide. Yttrium barium copper oxide and YttriumIII oxide. Yttrium Barium Copper Oxide Synonyms YBCO YBa 2 Cu 3 O 7-x Y123 barium copper yttrium oxide YBaCuO yttrium barium cuprate YBa2Cu3Ox Y1Ba2Cu3O6x YBa2Cu3Ox YBa2Cu4Oy Y124Y2Ba4Cu7Oy Y247 REBCO REBCO.
YBa 2 Cu 3 O 7 Molar mass. The tetragonal form of YBCO is insulating and does not superconduct. Its structure comprises sheets of copper and oxygen atoms as.
66619 gmol Appearance Black solid Density. The chemical formula of YBCO is Y 1 Ba 2 Cu 3 O 7-δ also called 123. Yttrium barium copper oxide and University of Alabama in Huntsville.
Many YBCO compounds have the general formula YBa2Cu3O7x also. Chemical formula YBa 2 Cu 3 O 7 shown in Figure 2D. That is it loses all resistance to electric current at extremely low temperatures.
Its CAS number is 1304-28-5 and its molecular weight is 1533328 gmol. Yttrium barium copper oxide YBCO is a family of crystalline chemical compounds famous for displaying high-temperature superconductivity. Many YBCO compounds have the general formula YBa 2 Cu 3 O 7x although materials with other YBaCu ratios exist such as YBa 2 Cu 4 O y or Y 2 Ba 4 Cu 7 O y.
When x 1 the O1 sites in the Cu1 layer are vacant and the structure is tetragonal. These cases are illustrated by yttrium barium copper oxide YBCO. Increasing the oxygen content slightly causes more of the O 1 sites to become occupied.
It is a white hygroscopic formed by the burning of Ba metal in oxygen or the decomposition of the carbonate salt. 22102015 Properties IUPAC name Barium Copper Yttrium Oxide Chemical formula YBa2Cu3O7 Molecular mass 66619 gmol Appearance Black solid Density 63 gcm Melting point 1000 C Solubility in water Insoluble 8. This non-stoichiometry is denoted by the x in the chemical formula YBa 2 Cu 3 O 7-x.
When x 1 the O 1 sites in the Cu 1 layer are vacant and the structure is tetragonal. The tetragonal form of YBCO is insulating and does not superconduct. YBCO has an orthorhombic unit cell shown in the figure of lattice Ba α-β-γ-90.
For example yttrium barium copper oxide arguably the most notable high-temperature superconductor is a non-stoichiometric solid with the formula Y x Ba 2 Cu 3 O 7x. Melting point 1000 C Solubility in water. YBCO is a superconducting ceramic.
And-be-Ko is a commonly used high temperature superconductor of the second kind a well-known fact that he is first received a superconductor with a critical temperature of more than 77 K the boiling point of nitrogen. BaCO3 BaO CO2. Non-stoichiometric compound - Wikipedia.
Yttrium barium copper oxide YBCO chemical formula of Cu YBa2Cus07 is a family of crystalline chemical compounds known for their high-temperature superconductivity. This material a famous high-temperature superconductor achieved prominence because it was the first material to achieve superconductivity above the boiling point of nitrogen. The superconducting state of YBCO can vary from δ0 to 05.
This non-stoichiometry is denoted by the x in the chemical formula YBa 2 Cu 3 O 7-x. Youre then left with YBCO whose empirical formula has one atom of yttrium two of barium three of copper and seven of oxygen. Yttrium oxide also known as yttria is Y2O3.
Yttrium is a chemical element with symbol Y and atomic number 39.
