Copper Oxide (commonly called cupric oxide) is a fundamental inorganic compound with the molecular formula CuO, CAS number 1317-38-0, and molecular weight 79.55. As a leading copper oxide factory, we produce this product as a fine black powder—ideal for uniform dispersion in ceramic glazes and glass melts.
This compound exhibits exceptional thermal and chemical stability: it has a density of 6.313 g/cm³ and a high melting point of 1446℃, allowing it to withstand the extreme temperatures of ceramic firing and glass production. It is insoluble in water but dissolves in acids, ammonia water, and ammonium chloride—forming a blue solution that simplifies integration into acidic formulations. Its fine particle size (D50: 1-10μm) ensures it mixes evenly, avoiding clumps that could cause defects in end products.
Our Copper Oxide meets strict purity and performance standards to support high-quality ceramics and glass:
• Purity: Minimum 98% (ensures consistent color and chemical reactivity)
• Cadmium (Cd): Maximum 0.0005% | Lead (Pb): Maximum 0.005% (low heavy metals for safe, compliant products)
• Iron (Fe): Maximum 0.2% (prevents unwanted discoloration in ceramics/glass)
• Sulfate (SO₄⊃2;⁻): Maximum 0.1% | Hydrotrop (water-soluble substances): Maximum 0.1% (avoids defects like bubbles or streaks)
• Particle size (D50): 1-10μm (ensures uniform dispersion in glazes and melts)
With a melting point of 1446℃, our Copper Oxide remains stable during high-temperature ceramic firing and glass melting. It won’t degrade or evaporate, ensuring consistent color and performance in end products.
Ultra-low Cd, Pb, and Fe content means our Copper Oxide won’t cause discoloration or safety issues. This makes it suitable for food-contact ceramics (e.g., plates, mugs) and high-quality glass products.
The fine particle size (D50: 1-10μm) ensures the black powder mixes evenly into glazes and glass melts. This eliminates streaks, clumps, or uneven color—critical for achieving a smooth, professional finish.
Its ability to dissolve in acids, ammonia, and ammonium chloride lets you integrate it into a range of formulations. Whether you’re making ceramic glazes or specialty glass, it adapts to your process needs.
In ceramics, Copper Oxide is a key additive for glazes and bodies. It imparts rich blue-green hues to glazes, enhancing the aesthetic appeal of tiles, pottery, and decorative ceramics. Its thermal stability ensures the color remains vibrant even after high-temperature firing.
For glass production, it acts as a colorant and flux. It adds blue-green tones to decorative glass (e.g., stained glass, bottles) and helps lower the melting point of glass batches—reducing energy costs and production time. It also improves glass durability, making it more resistant to chemical corrosion.
Our standard packaging is net 25kg bags with pallets (40 bags/1000kg/pallet) for efficient storage and transport. We also offer 25kg drums for customers needing extra protection against moisture or contamination.
Yes! We provide a certificate of analysis (COA) for every batch, detailing parameters like purity, heavy metal content, and particle size. We also support third-party testing (e.g., SGS, BV) if you require additional verification.
Absolutely. Our product has ultra-low heavy metal levels (Cd≤0.0005%, Pb≤0.005%), complying with global standards for food-contact materials. It’s safe for use in ceramics like plates, bowls, and mugs.
Our MOQ is 1 ton, but we can accommodate smaller orders for sample testing or trial production. Contact our team to discuss your specific needs.
As a dedicated copper oxide factory, we have years of experience manufacturing high-purity copper compounds. Our production process is optimized to deliver consistent quality, batch after batch.
We source raw materials directly and use efficient manufacturing methods to keep costs low. This lets us offer premium Copper Oxide at affordable prices—ideal for large-volume applications like ceramic tile production.
Our production process is designed to minimize waste and reduce carbon emissions. We comply with all environmental regulations, making our Copper Oxide a sustainable choice for eco-conscious businesses.
We’ve partnered with major domestic manufacturers, state-owned enterprises, and private customers—earning a reputation for reliability and quality. Our customers trust us to deliver on time and meet their exact specifications.
Our team of experts provides personalized support. Whether you need help adjusting particle size, understanding regulatory requirements, or troubleshooting formulation issues, we’re here to assist. We don’t just supply products—we help you succeed.
