APPLICATIONS:
Cuprous Oxide (Red): Fungicides, in anti-fouling paints for
marine use, in photo electric cells, as Red pigment for glass,
ceramic glazes, in brazing paste, as catalyst in rectifiers.
Cupric Oxide (Black): As pigment for glass, ceramics,
enamels, porcelain glazes, artificial gems, in manufacturing of
rayon, and other copper compounds, in galvanizing electrodes,
influx in copper metallurgy, in soil application, in
anti-fouling paints, as catalyst in organic reactions. |
