11. :: : : Maybe the rain dissolves the peroxide to make oxygen and copper oxide . 12. :It was probably a demonstration of a YBCO ( yttrium barium copper oxide ) superconductor. 13. The early work was utility wares including copper oxide . 14. "' Tin-glazed pottery "'is earthenware covered in copper oxide , iron oxide, manganese dioxide and antimony oxide. 15. Too much of the copper ingredients results in excesses of copper oxides like cuprite and tenorite. 16. By 1899 Mt Garnet Freehold Copper and Silver Mining Company was producing high grade copper oxide . 17. The superconductor is bismuth strontium calcium copper oxide ( BSCCO ) which superconducts at liquid nitrogen temperatures. 18. Copper salts, including copper gluconate, copper acetate, or copper sulfate, are more easily absorbed than copper oxides . 19. Cuprate superconductors usually feature copper oxides in both the oxidation state 3 + as well as 2 +. 20. Wires made of copper oxide can achieve superconductivity at higher temperatures than carbon-60, but the material is expensive.
