Zirconia Alumina Compound Grinding Media, encompassing Zirconia Toughened Alumina (ZTA) and Alumina Toughened Zirconia (ATZ), represent two categories of ceramic grinding media renowned for their superior wear resistance and high-performance attributes.

ZTA grinding media is forged from a blend of alumina and zirconia. The infusion of zirconia during fabrication enhances the material’s toughness and strength, rendering it highly resistant to wear and ideal for applications demanding top-tier performance in grinding.

Conversely, ATZ grinding media is formulated from a combination of zirconia and alumina. The inclusion of alumina during the manufacturing process bolsters the material’s strength and toughness, resulting in exceptional wear resistance suitable for rigorous grinding applications.

Both ZTA and ATZ grinding media find extensive utility across various industries, including the production of electronic materials and advanced ceramics, as well as mining and mineral processing. They exhibit outstanding performance in both wet and dry grinding processes and are offered in diverse sizes and shapes to cater to distinct application needs.

Sanxin introduces Zirconia Alumina Compound, a toughened grinding media crafted from premium-grade and ultra-fine yttria zirconium powder alongside alumina powder. These products possess elevated wear resistance and strength owing to the exceptional toughness of zirconia. The attributes and specifications of these grinding media align with international advanced standards.


Standard Size Range: ZTA is available within a standard size range spanning from 2.0 to 15 mm, ensuring versatility across various applications.

Exceptional Wear Resistance: Rigorous wear rate tests demonstrate ZTA’s superiority, showcasing 4 to 30 times greater wear resistance compared to various high-quality high-alumina (90–92% Al2O3) grinding media available globally.

Density Parity: ZTA boasts a comparable density to high-alumina media, making it an exceptional substitute without compromising on performance.

Superior Performance-Price Ratio: ZTA offers an impressive performance-price ratio, delivering superior functionality while effectively reducing costs for end-users.
