Chemical compound
Copper(II) borate is an inorganic compound with the formula Cu 3(B O 3)2. It consists of copper atoms in their cupric oxidation state and orthoborate groups. In the 19th century it was proposed to be used as a green pigment to replace the very toxic paris green.[3] It has been studied for it photocatalytic properties.[2]
Preparation
[edit ]Copper(II) borate can be prepared by heating a stoichiometric mixture of copper(II) oxide and diboron trioxide to 900 °C.[2] [1]
- 3CuO + B2O3 → Cu3(BO3)2
