Bismuth strontium calcium copper oxide Bi2Sr2CanCun+1O2n+6
A family of high-temperature superconductors and also the first high-temperature superconductors to be discovered which did not contain a rare earth element.
Copper gluconate C12H22CuO14
Dietary supplement -- metabolizable copper to treat copper deficiency. Used to treat acne vulgaris, common cold, hypertension, premature labor, Leishmaniasis, visceral postoperative complications.
Copper(II) arsenate Cu3(AsO4)2.4H2O or Cu5H2(AsO4)4.2H2O
Is an insecticide used in agriculture, also used as a herbicide, fungicide, and a rodenticide.
Copper(II) bromide CuBr2
It is used in photographic processing as an intensifier and as a brominating agent in organic synthesis.
It is also used in the copper vapour laser, a class of laser where the medium is copper bromide vapour formed in situ from hydrogen bromide in reaction with the enclosing copper discharge tube. [2] Producing yellow or green light, it is used in dermatological applications.
Copper indium gallium selenide (CIGS) Cu(Ga,In)Se2
CIGS is a new semiconductor used mainly in photovoltaic cells (CIGS cells).
CIGS solar cells are not as efficient as crystalline silicon solar cells, but they are expected to be substantially cheaper. CIGS can be printed directly onto molybdenum coated glass sheets. Solar cells made from crystalline silicon are made of slices of solid silicon and require therefore more expensive semiconductor material.
Copper(II) sulfate CuSO4.5H2O
It can be used to plate metals with copper, as a fungicide or herbicide, or as a chemical test for water (the anhydrous form will absorb water, turning blue).
Copper sulfate is also used to test blood for anemia. A drop of the patient's blood is dropped into a container of copper sulfate, if it sinks within a certain time, then the patient has sufficient haemogloblin levels and is not anemic. If the blood floats or sinks too slowly, then the patient is iron-deficient and may be anemic.
Verdigris Cu(CH3COO)2
It commonly occurs by the action of acetic acid when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. Its name comes from the Middle English vertegrez, from the Old French verte grez, an alteration of vert-de-Grice - verd (green), de (of), and Grice (Greece)- "green of Greece".
The vivid green colour of verdigris makes it a very common pigment. Until the 19th century, verdigris was the most vibrant green pigment available and frequently used in painting. Verdigris is lightfast in oil paint, as numerous examples of 15th century paintings show. However, its lightfastness and air resistance is very low in other media. Copper resinate, made from verdigris, is not lightfast, even in oil paint. In the presence of light and air, green copper resinate becomes stable brown copper oxide.
