Copper I Oxide Formula, Properties & Structure Study.com
Copper(I) oxide may be produced by several methods. Most straightforwardly, it arises via the oxidation of copper metal: 4 Cu + O2 → 2 Cu2O Additives such as water and acids affect the rate of this process as well as the further oxidation to copper(II) oxides. It is also produced commercially by reduction of … Meer weergeven Copper(I) oxide or cuprous oxide is the inorganic compound with the formula Cu2O. It is one of the principal oxides of copper, the other being or copper(II) oxide or cupric oxide (CuO). Cuprous oxide is a red-coloured … Meer weergeven The solid is diamagnetic. In terms of their coordination spheres, copper centres are 2-coordinated and the oxides are tetrahedral. … Meer weergeven In the history of semiconductor physics, Cu2O is one of the most studied materials, and many experimental semiconductor applications … Meer weergeven Cuprous oxide is commonly used as a pigment, a fungicide, and an antifouling agent for marine paints. Rectifier diodes based on this material have been used industrially as early as 1924, long before silicon became the standard.
