• Description: Yttrium barium copper oxide (YBCO) is a crystalline compound with important property of high temperature superconductor above the boiling point (77 K) of liquid nitrogen. YBCO is sensitive to air and moisture. Exposures to YBCO have been reported to cause skin irritation, serious eye irritation, and respiratory irritation. Symptoms of systemic copper poisoning may include capillary damage, headache, cold sweat, weak pulse, kidney and liver damage, central nervous system excitation followed by depression, jaundice, convulsions, paralysis, and coma. Death may occur from shock or renal failure. Chronic copper poisoning is typified by hepatic cirrhosis, brain damage and demyelination, kidney defects, and copper deposition in the cornea as exemplified by humans with Wilson s disease. It has also been reported that copper poisoning has led to haemolytic anaemia and accelerates arteriosclerosis.

Technology Process of Barium copper yttrium oxide

There total 2 articles about Barium copper yttrium oxide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Guidance literature:

With O₂; In neat (no solvent); Prepn. by stacking layers of CuOx, Y2O3, and BaF2 onto substrates held at room temp.. The CuOx layer was obtained by oxidizing in air a previously deposited Cu film. Y2O3 layer was grown by evapn. of Y in vac. Annealing (880°C in flowing oxygen).;
