Cupric oxide CAS#1317‑38‑0
Copper(II) oxide delivers blue‑green pigmentation for ceramics. A naturally occurring mineral obtained through mining, it serves as a precursor for copper‑based products such as fungicides and wood preservatives. It can be incorporated into antifouling paints for boat hulls and outdoor wooden structures exposed to fresh‑water and seawater environments.
Though occasionally utilized in animal feed, it is not an ideal choice, since its copper bioavailability is lower compared with alternatives including cupric acetate and basic copper carbonate. Further applications involve the manufacturing of superconductors, batteries, and it functions as a catalyst in numerous industrial processes.

<h2>Product Application</h2>
<h3>Glass, Enamel & Ceramic Industry</h3>
Cupric oxide acts as a stable colorant to produce blue‑green shades in glazes and ceramic bodies. It also serves as a polishing agent for optical glass and anti‑wrinkle additive for paint formulations. It is widely adopted for making colored glass, artistic enamel ware and decorative ceramic products.
<h3>Chemical Catalysis & Oil Processing</h3>
It works as an organic synthesis catalyst, hydrogenation agent and petroleum desulfurizer. It can remove sulfur impurities from fuel oil and grease. It is also used as a carrier for other organic catalysts and raw material for manufacturing various copper compounds.
<h3>Analytical & Rayon Production</h3>
Cupric oxide is used for gas analysis and carbon/nitrogen detection in organic testing. It is a key raw material in the production of artificial silk (rayon). It can also be used to prepare artificial gemstones.
<h3>Nutrient & Feed Additive</h3>
Copper is an essential trace nutrient. It supports iron absorption, red blood cell formation and bone health maintenance. Note that cupric oxide has relatively low copper bioavailability compared with cupric acetate and basic copper carbonate, so it is not the first choice for high‑efficiency feed supplementation.

<h2>FAQ</h2>
<h3>Q: Can cupric oxide be used directly as animal feed copper source?</h3>
A: Yes, it can be added, but its copper bioavailability is low. For better absorption, cupric acetate or basic copper carbonate is more recommended.
<h3>Q: Is sample available?</h3>
A: Yes, small trial samples are available. Sample freight can be negotiated.
<h3>Q: What documents can you provide?</h3>
A: COA, MSDS, commercial invoice, packing list, and support SGS test report.
<h3>Q: How to store cupric oxide?</h3>
A: Store in cool, dry and ventilated warehouse. Keep tightly closed, avoid moisture and strong acid materials.
