Core Product: Active Ultra-Low Sodium α-Al₂O₃ Micro Powder for Ceramic Coatings
To meet the rigorous demands of ceramic coating applications, Shandong Greatsun Aopeng Group has engineered the 06 Series Reactive Ultra-Low Sodium $\alpha$-Al₂O₃ Micropowder.
Defined by its core strengths—exceptional purity, minimal impurity levels, and high reactivity—this versatile product is tailored for a wide spectrum of ceramic coatings, including wear-resistant ceramic coatings, high-temperature glazes, and functional filler-based coatings. It not only significantly elevates overall coating performance but also offers the formulation flexibility needed to fulfill customized application requirements.
Core Product Advantages
Compared with ordinary calcined alumina powder,Greatsun Aopeng's alumina powder for ceramic coatings has four core advantages, precisely matching the R&D and production needs of high-end ceramic coatings:
1.Its outstanding low-sodium characteristic is that the sodium content is ≤ 0.03% (300ppm), which is far lower than that of ordinary calcined alumina powder. This effectively avoids the impact of sodium on the sintering performance and temperature resistance of ceramic coatings, reduces problems such as coating cracking and peeling, and improves the stability and service life of the coating.
2.High activity and easy sintering: The product has high activity and good sintering performance. In the process of ceramic coating preparation, it can quickly integrate with other components to form a dense coating structure, which significantly improves the hardness, wear resistance and corrosion resistance of the coating.
3. Uniform Particle Size and Easy Dispersion: The median particle size (D50) can be flexibly customized between 1-5μm, resulting in a concentrated particle size distribution and excellent dispersibility. This ensures uniform dispersion within the coating system, preventing clumping and sedimentation, and guaranteeing smooth application and a smooth coating finish.
4. High Purity and Stable Quality: With an Al₂O₃ content ≥ 99.5% and extremely low impurity content, the product meets the environmental requirements of high-end ceramic coatings. Furthermore, the manufacturing process strictly adheres to ISO quality system standards, ensuring batch-to-batch quality stability and providing reliable assurance for coating production.
