High-density (6.0 g/cm³), mirror-polished 95% yttria-stabilized zirconia (3Y-TZP) grinding balls/beads and planetary ball-mill jars for ultra-low-wear, iron-free sub-micron milling.
High-energy planetary ball milling and stirred bead milling of battery active materials (LFP, NMC, sulfide/oxide solid electrolytes), piezoelectric/structural ceramics, phosphors, and pharmaceuticals cannot tolerate ppm iron contamination from steel balls or rapid silica/alumina wear from cheaper media. Sintered 3 mol% yttria-stabilized zirconia (95% ZrO2, 6.0 g/cm³) delivers 65% higher kinetic impact energy than alumina at 10–30× lower ppm wear rates.
We supply both mirror-polished spherical grinding media (0.1 mm micro-beads through 20–30 mm balls) and matching O-ring-sealed planetary mill jars (50, 100, 250, 500, and 1,000 mL, including glovebox vacuum/inert gas valve lids), plus agate, tungsten carbide, alumina, and PTFE jars.
| Property / Metric | Nominal Reference Value (Grade Dependent) |

| Composition | 94.7% ZrO2 (+HfO2) / 5.2% Y2O3 (true 3Y-TZP; zero ceria discoloration) |
| Specific Gravity / Density | ≥6.00 g/cm³ |
| Vickers Hardness & Toughness | ≥1,250 HV10; ~9.0 MPa·m½ (crush & chip resistant) |
| Media Sizes Stocked | 0.1, 0.3, 0.5, 1, 2, 3, 5, 8, 10, 15, 20, 25 mm diameters |
| Planetary Jar Volumes | 50, 100, 250, 500, 1,000 mL (Viton, Silicone, or PTFE gaskets) |
Reference values reflect typical sintered, fused, or wrought grades. Exact batch test figures are confirmed on your written quotation and accompanying lot Certificate of Analysis.
For grinding media, specify ball diameter(s)—many labs combine e.g. 3 mm + 5 mm + 10 mm balls—and weight per size (500 g, 1 kg, 5 kg). For planetary jars, specify volume (mL), planetary mill brand/clamp height (Retsch, Fritsch, Across International, MSE/generic), solid ceramic vs. 304SS protective jacket, gasket elastomer, and whether vacuum/inert-gas purge valves are needed.
Include target quantity, destination country/postal code for express air freight calculation, and any special cleanroom bagging or certification requests.
