Our Black Cement Oxide is a high-purity black powder pigment. We manufacture it specifically for the concrete and construction materials industry. This product is more than a simple coloring agent. It is a stable functional material that provides long-lasting color for cement-based products. Our customers use it to produce high-quality concrete goods, paving bricks, decorative blocks, and terrazzo flooring.
They choose our pigment because it does not only color the surface. It gives the entire material a deep and consistent black appearance. The color remains uniform throughout each batch. When you use our Black Cement Oxide in your production line, it helps maintain stable color performance and reduces color variation.
We manufacture this product at our factory in Fuyang, Hangzhou. We operate a complete production line and a 1,000-square-meter R&D laboratory. Our technical team consists of 15 members, all holding bachelor's degrees or above. The team leader has a postdoctoral degree and is recognized as a Hangzhou Class D talent.
Our factory has maintained stable operations for 5 years. We control quality from the beginning of the production process. We start by recovering iron resources from acid pickling waste liquid and carefully monitor every production step until the finished product leaves our factory.
Each batch undergoes complete visual inspection and performance testing before shipment. We provide a COA report with every delivery, allowing you to trace product quality back to the source.
The table below shows the key technical parameters of our Black Cement Oxide. These specifications demonstrate why this product performs well in cement applications. The low volatile matter content helps reduce moisture absorption. The low water-soluble matter content ensures good dispersion. The low sieve residue helps achieve smooth mixing without clumping.
