Cuprous Oxide (also known as copper oxide red or cupric oxide red) is a versatile inorganic compound with the molecular formula Cu₂O, CAS number 1317-39-1, and molecular weight 143.08. As a trusted cuprous oxide supplier, we produce this product in multiple forms: red powder, crystals, or pellets (monophase powder)—each tailored to different application needs.
This compound boasts impressive physical properties: it has a density of 6.04 g/cm³ and a high melting point of 1232℃, making it stable under high-temperature processing (common in ceramics and glass production). It is insoluble in water but dissolves in acids— a trait that simplifies formulation in acidic coatings (e.g., ship bottom paints). Its vibrant red color also makes it a natural choice for pigment applications, as it delivers long-lasting hue without fading.
Our Cuprous Oxide meets rigorous purity standards to ensure performance across industries:
• Reduction degree (by Cu₂O): Minimum 98% (guarantees high reactivity in coatings and pigments)
• Assay (by Cu₂O): Minimum 97% (ensures consistent color and performance in end products)
• Copper (metal): Maximum 1% (low free metal content prevents unwanted reactions)
• Copper (total): Minimum 87% (delivers optimal pigment strength and coating efficacy)
• Chloride (Cl⁻): Maximum 0.5% | Sulfate (SO₄⊃2;⁻): Maximum 0.5% (low impurities avoid defects in ceramics/glass)
• Moisture (H₂O): Maximum 0.5% (prevents clumping in powder form)
• Mesh residue (500mesh): Maximum 0.3% (ensures fine texture for smooth coatings and uniform pigment dispersion)
With assay and reduction degrees above 97% and 98% respectively, our Cuprous Oxide delivers uniform color and performance. This eliminates batch-to-batch variations, critical for industries like ceramics where consistency is key.
Our production process is designed to reduce waste and minimize environmental impact. Unlike some pigment manufacturers, we avoid toxic byproducts—making our Cuprous Oxide a sustainable choice for eco-conscious businesses.
We offer Cuprous Oxide in powder, crystal, or pellet form. This flexibility lets you choose the best format for your process: powder for smooth coatings, pellets for high-temperature ceramic firing, or crystals for specialized glass applications.
Our efficient manufacturing process allows us to offer high-purity Cuprous Oxide at competitive prices. You get premium quality without sacrificing your budget—ideal for large-volume applications like ship coatings or ceramic production.
Cuprous Oxide is a key ingredient in ship bottom paints. It releases copper ions slowly, which repel barnacles, algae, and other marine organisms. This protects the ship’s hull from damage, reduces drag, and improves fuel efficiency.
In the ceramic industry, it acts as a vibrant red pigment. It withstands high firing temperatures (up to 1232℃) without fading, creating rich, long-lasting colors in pottery, tiles, and decorative ceramics.
For glass and enamel production, it adds a blue-green or red hue (depending on formulation). It also improves the durability of glass, making it resistant to scratches and chemical corrosion—ideal for decorative glass or industrial enamel coatings.
Our standard packaging is net 25kg bags with pallets (40 bags/1000kg/pallet) for easy storage and transport. We also offer 25kg drums for customers needing extra protection. All packaging complies with CLASS 9 UN3077 regulations for hazardous materials.
Yes! We can adjust the mesh size (beyond the standard 500mesh) to match your needs—whether you require finer powder for smooth coatings or coarser particles for specialized ceramic mixes.
Absolutely. Our product has low heavy metal and impurity levels, complying with global standards for coatings, ceramics, and glass. We also provide safety data sheets (SDS) to help you meet regulatory requirements.
We send free samples within 3 working days. This lets you test color, solubility, and performance before placing a bulk order.
We offer a full line of copper products, including Cuprous Oxide, Copper Chloride Basic, and Copper Oxide. This lets you source all your copper-based materials from one trusted supplier, simplifying your supply chain.
We strictly control every step of production—from raw material selection to final testing. Our QC team ensures every batch meets our high standards, so you can use our Cuprous Oxide with confidence.
We focus on continuous improvement, investing in new technologies to enhance product quality and reduce environmental impact. Our goal is to deliver solutions that help your business stay competitive.
Our team provides end-to-end support: from helping you choose the right product form to assisting with customs documentation. We’re committed to building long-term partnerships, not just making sales.
