| 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.
