烧结硅酸锆(SZS)研磨介质,4.0–5.0 mm。用于球磨机和初步分散的粗磨介质。密度高于氧化铝,且压碎强度达 ≥1,400 N,强度优于氧化锆增韧氧化铝(ZTA),而成本仅为稳定氧化锆的一小部分。在此珠径下,增加的压碎强度至关重要,因为单次碰撞的冲击载荷最大。
| 材质 | 烧结硅酸锆 |
| 化学成分 | Al₂O₃ + ZrO₂ ≥ 67% SiO₂ ≤ 30% 其他 ≤ 3% |
| 珠径 | 4.0–5.0 mm |
| 密度 | ≥ 4.08 g/cm³ |
| 维氏硬度 | ≥ 10 GPa |
| 压碎强度 | ≥ 1,400 N |
| 磨耗损失 | ≤ 1.2 g/kg·h |
| 球度 | ≥ 95% |
| 吸水率 | ≤ 0.01% |
| 外观 | 浅黄色 |
球磨机、辊磨机和搅拌磨。适用于湿法和干法研磨。如需中等程度和精细分散,请改用 2.5–2.8 mm 介质。
硅酸锆的性能介于氧化铝和稳定氧化锆之间。它比氧化铝研磨效率更高且寿命更长,成本远低于氧化锆,但其较低的密度限制了在高粘度系统中的能量传递,且不适用于对锆、铝或硅污染有严格要求的环境。如需处理电池材料、电子陶瓷或制药,请使用钇稳定或铈稳定氧化锆。
按公斤销售。有 1–13 mm 规格可选。亦提供 2.5–2.8 mm 规格。如需批量定价或获取介质匹配流程的协助,请联系我们。
