YSZball-S High-Purity Yttrium Stabilized Zirconia Milling Balls, Uniform Diameter 0.3-20 mm, 1 kg Pack
YSZball-S milling balls are engineered for precise laboratory milling applications requiring consistent grinding media size and high material purity. These balls are made from 99.5% yttrium stabilized zirconia (YSZ), a ceramic material known for its exceptional hardness and chemical stability, making it ideal for use in ball milling machines where contamination and wear resistance are critical.
The YSZball-S series offers a wide range of selectable diameters from 0.3 mm up to 20 mm, each sold in 1 kg quantities with uniform ball size to ensure reproducible milling results. The typical Vickers hardness of these balls ranges between 12 and 12.3, providing durable performance under rigorous milling conditions. The tight diameter tolerances (±0.1 to ±0.5 mm depending on size) support uniform grinding efficiency and minimize variability in particle size reduction processes.
