Ceramic Grinding Media Balls Performance Comparison:
| ZrO2 | Al2O3 | Si3N4 | SiC |
| zirconium oxide (ZrO2)， yttria (Y2O3) | aluminium oxide ( High Purity） | silicon nitride (Si3N4) | silicon carbide (SiC) |
| 6.0 g/cm³ | 3.75-3.95 g/cm³ | 3.2 g/cm³ | 3.0 – 3.2 g/cm³ |
| low, 2-3 W/m·K | middle，20-30 W/mK | 15 – 50 W/mK | high, 100–120 W/m·K |
| 5-6 kgs/Ton | Very High | Low | Very Low |
| Used in various grinding processes such as ball milling and abrasive wear, which require high wear resistance and minimal contamination, including applications in ceramics, pigments, pharmaceuticals, and cosmetics. | As grinding media in ball mills, Chutes, pipelines, and pump impellers. Thermocouple protection in furnaces. |
Request hard material grinding and high-temperature grinding processes, high wear resistance, such as in silicon nitride ceramic powder, metal processing in the automotive industry. | Metal precision finishing, ceramic grinding, and glass cutting. |
Ceramic Grinding Media Balls Sintering Way Comparison:
| Gas Pressure Sintering (GPS) | Hot Isostatic Pressing Sintering (HIP) | |
| Sintering Condition | Temperature: 1800–1900℃ | Temperature: 1800–1900℃ |
| Sintering atmosphere pressure: 10 MPa | Sintering atmosphere pressure: 200 MPa | |
| Degree of Densification | Residual minor porosity (99.2%) | Near full densification (99.8%) |
| Performance Indicators | Meet Grade II–III Ball Standards | Performance indicators and fatigue life are significantly improved compared to GPS. |
| ASTM F2094-2011 (USA) | Grade III | Grade I, II |
| Grade | Medium–Low Pressure Ceramic Balls | High-End Ceramic Balls |
| Remarks | Technology predominantly used domestically | Commonly adopted internationally, but with high costs, not suitable for large-scale industrial production. |
Ceramic Grinding Media Balls Production Process:
Ultra-fine High-purity Silicon Nitride Powder, Sintering Aids, Additives → Homogeneous Mixing → Spray-dried Granules → Cold Isostatic Pressing (CIP) → Green Body Machining → Sintering (Isostatic Pressing (HIP) or Gas Pressure Sintering (GPS))→Balls Blank Inspection→Coarse Grinding, Precision Grinding, Ultra-fine Processing.
