Cuprous Oxide |
| Cuprous oxide (Cu2O) is an oxide of copper also known as Copper(I) oxide. It
is insoluble in water and organic solvents. We are manufacturing it by electrolysis method. Cuprous oxide
is commonly used as a pigment, a fungicide and an antifouling agent for
marine paints. It is used in agricultural fungicide, seed dressing; In
Mineral supplements against an insufficiency of copper in the diet of
animals, colorant for porcelain, glazes and glass.As an catalyst in various dyes and pharmaceutical industries. Cuprous oxide was the
first substance known to behave as a semiconductor. The biological property
of copper compounds takes important role in as fungicides in agriculture and
biocides in antifouling paints for ships and wood preservations. |

Cupric Oxide |
|
| |
Cupric Oxide (copper (II) oxide CuO) is a black crystal. It is used in
making fibers, ceramics, gas analyses and for Welding fluxes. Cupric Oxide
is used as a catalyst and in catalyst preparation. Cupric Oxide (CuO) is the
higher oxide of copper. Cupric oxide is used as a pigment in ceramics to
produce blue, and green glazes. Cupric oxide is used as flux in copper
and bronze metallurgy, in galvanic electrodes, as solvents for chromic iron
ores,and also used in manufacturing wood preservatives. |
