Import 21 Mm Yt-Stabilized Zirconia Bead — Buy in wholesale FOB from Supplier in China

The 21mm yttria-stabilized zirconia grinding bead is a premium ceramic grinding media designed for high-performance milling applications in vertical stirring mills and horizontal roll mills. This specific bead size (21mm diameter) places it in the large-media category suitable for coarse grinding applications and larger batch processing. The yttria stabilization (3 mol% Y2O3 in ZrO2) provides the tetragonal crystal structure that gives these beads exceptional toughness and resistance to crack propagation, making them superior to traditional alumina or glass grinding media for demanding applications.

The yttria-stabilized zirconia (YSZ) composition offers high density (typically 6.0-6.1 g/cm3 for 3mol% Y2O3 grade), exceptional wear resistance, and minimal contamination during milling due to zirconia's chemical inertness. These properties make YSZ beads the preferred choice for applications where product purity is critical, including ceramic slurries, mineral processing concentrates, electronic component materials, and pharmaceutical intermediates. The 21mm size is optimized for larger particle grinding and higher throughput processing, where smaller beads would require longer milling cycles. The listing indicates these beads are industrial grade with low wear rate, reducing contamination and frequency of media replacement.

Buyers of YSZ grinding beads include ceramic manufacturers, mineral processing operations, pharmaceutical companies, electronics material producers, and paint and coating manufacturers. The 21mm size is particularly suited for horizontal roll mills used in ceramic tile production and large-scale mineral processing operations. Import considerations include verifying the exact yttria content (which affects toughness and thermal expansion characteristics), confirming density and sphericity specifications, and establishing quality control protocols for incoming inspection. The listing indicates ISO and SGS certifications, and payment terms including L/C and T/T.

Zibo Win-Ceramic Material Co. Ltd is located at No. 22, Changguo Western Road, Zhangdian District, Zibo City, Shandong Province, China 255000. The Zibo area in Shandong Province is recognized as a significant manufacturing center for ceramic materials and industrial ceramics in China. The listing indicates a trust tier classification of harbor without specific response rate data. The supplier specializes in ceramic grinding media and advanced ceramic materials.

The supplier offers yttria-stabilized zirconia grinding beads as a core product category, indicating manufacturing specialization in ceramic media rather than broad industrial supplies. The listing mentions ISO and SGS certifications, suggesting quality management system compliance. Trade terms indicated include FOB and CIF shipping options with payment methods of L/C (Letter of Credit) and T/T (Telegraphic Transfer). The listing does not specify production capacity, minimum order quantities, or specific export market experience. Buyers should verify certification validity and request recent test reports for key parameters.
