2. Copper(I) phosphide - Wikipedia

   en.wikipedia.org/wiki/Copper(I)_phosphide

   Recent crystallographic investigations have proven Cu 3 P to be copper deficient, which means that the sum formula of this compound is more accurately expressed as Cu 3−x P. [4] Copper phosphide has a role in copper alloys, namely in phosphor bronze. It is a very good deoxidizer of copper.

   In Cs 2 CuCl 4, CuCl 4 2− exhibits a distorted (flattened) tetrahedral geometry, whereas in [Pt(NH 3) 4][CuCl 4], it adopts a planar configuration. Green CuBr 3 − and violet CuBr 4 2− are also known. [9] Monovalent copper forms luminescent Cu n X n clusters (where X = Br, Cl, I), exhibiting diverse optical properties. [10] [11]

5. Oxygen-free copper - Wikipedia

   en.wikipedia.org/wiki/Oxygen-free_copper

   Conductivity is generally specified relative to the 1913 International Annealed Copper Standard of 5.8 × 10 7 S/m. Advances in the refining process now yield OF and ETP copper that can meet or exceed 101% of this standard. (Ultra-pure copper has a conductivity of 5.865 × 10 7 S/m, 102.75% IACS.) Note that OF and ETP coppers have identical ...

   Example of a copper alloy object: a Neo-Sumerian foundation figure of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA)

7. List of copper salts - Wikipedia

   en.wikipedia.org/wiki/List_of_copper_salts

   Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color . Copper also has a range of different organic and inorganic salts , having varying oxidation states ranging from (0,I) to (III).

8. Copper silicide - Wikipedia

   en.wikipedia.org/wiki/Copper_silicide

   Copper silicide can refer to either Cu 4 Si [2] or pentacopper silicide, Cu 5 Si. Pentacopper silicide is a binary compound of silicon with copper. It is an intermetallic compound, meaning that it has properties intermediate between an ionic compound and an alloy. This solid crystalline material is a silvery solid that is insoluble in water.

9. Copper(II) hydroxide - Wikipedia

   A purer product can be attained if ammonium chloride is added to the solution beforehand to generate ammonia in situ. [10] Alternatively it can be produced in a two-step procedure from copper(II) sulfate via "basic copper sulfate:" [9] 4 CuSO 4 + 6 NH 3 + 6H 2 O → Cu 4 SO 4 (OH) 6 + 3 (NH 4) 2 SO 4 Cu 4 SO 4 (OH) 6 + 2 NaOH → 4 Cu(OH) 2 ...
