copper oxide

Dangerous for fish, because of copper oxide dissolving in water.

The addition of copper oxide at 2-3% produces a turquoise colour.

This is done by blowing natural gas through the molten copper oxide.

It has now become clear that sheets of copper oxides are a key to the new superconductors.

The new superconductors all contain copper oxides, which contribute oxygen to the process.

Whatever the cause, the color from the copper oxide heightens the delicacy of the decoration.

Copper oxide and selenium rectifiers were developed for power applications in the 1930s.

The bulk of the copper oxide is turned back into the form of sulfide.

Ultramarine withstands heat, but azurite turns to black copper oxide.

Copper oxide is a compound from the two elements copper and oxygen.

Copper oxide can refer to either of these compounds:

High-temperature superconductors, made of copper oxides, tend to be brittle, however.

Up until late February, all known high-temperature superconducting materials were some variation of a copper oxide.

January 11: Owen dies from copper oxide poisoning and his body is thrown overboard.

Both use copper oxides as active ingredients.

The green colour of Saintonge comes from Copper oxide, added to the clear lead glaze finish.

In the presence of light and air, green copper resinate becomes stable brown copper oxide.

Copper oxides, oxy-chlorides, and sulfides are dark-colored films on the surface.

Some things to watch out for are copper oxides from water and air, leftover sulfur from sulfate.

Similar to copper oxide heap leaching, also using dilute sulfuric acid.

Starting with copper oxide, proceeding to germanium, then silicon, the materials were systematically studied in the 1940s and 1950s.

It starts immediately on exposure to the environment with the initial formation of copper oxide conversion films that are noticeable within six months.

They are typically white or buff, with one area (called Fairyland) tinted a light blue, perhaps by copper oxides.

This step exploits the relatively easy reduction of copper oxides to copper metal.

No commercial applications exist for yttrium barium copper oxide.
