What is Zinc Oxide? Zinc oxide (ZnO) is a white, inorganic powder used in a variety of high-performance industries including ceramics, electronics, rubber compounding, cosmetics, glass manufacturing, and advanced coatings. Its optical, chemical, and antimicrobial properties make it valuable in both consumer and industrial-grade applications. The particle size of zinc oxide is critical in determining its functionality—especially in UV protection, dielectric properties, and catalytic behavior.
Uniform particle size is crucial for achieving consistency in dispersion, surface reactivity, and end-use performance. For example, rubber and tire manufacturers rely on tight particle distributions for better curing behavior, while ceramic and electronic industries require high-purity, finely sieved ZnO to ensure defect-free sintering and stable conductivity. Typical size requirements range from 50 microns down to sub-10 micron levels, depending on the application. Traditional sieving equipment often fails with zinc oxide due to clumping, electrostatic behavior, and mesh blinding, especially when screening fine powders.
Elcan Industries has screened zinc oxide powders for use in ceramics, glass, specialty chemicals, and battery research. Using our Hi-Sifter high-energy screening system, we provide reliable sizing down to 10 microns, even for batches with a tendency to agglomerate or blind mesh. The vertical energy of the Hi-Sifter ensures powder fluidity and consistent throughput without compromising accuracy. For finer classifications or when screens are a limiting factor, our Elbow Jet Air Classifier offers a no-screen solution capable of separating zinc oxide powders down to 1 micron, ideal for nanostructured ZnO or advanced R&D needs. Additionally, our CG Electromagnetic Separator removes metallic contaminants, ensuring high-purity, electronics-grade output.
