Copper Oxide Black

We are manufacture of high purity copper oxide (cuo) powder. Our copper oxide is offered in cupric oxide black (powder form). Technical specification- metal contents 80%, oxygen 20%. It is used as a pigment in ceramics to produce blue, red, and green in glasses, enamels, clay glazes and sometimes gray, pink, or black glazes. Cupric oxide is used to produce dry cell batteries, also in rubber industry.
Cobalt or copper oxide for all shades of blue & black and copper and chrome oxide for all green shades.
Cupric oxide chemistry: total cu= 78.5% min., cuo= 98% min. And cu2o= 3% max.
Another use for cupric oxide is as a substitute for iron oxide in thermite. This can turn the thermite from an incendiary to a low explosive.
It virtually insoluble in water or alcohols; copper(ii) oxide dissolves slowly in ammonia solution but quickly in ammonium carbonate solution; it is dissolved by alkali metal cyanides and by strong acid solutions; hot formic acid and boiling acetic acid solutions readily dissolve the oxide.
