帝诺复合锆球DURA-37：
DURA-37 复合锆球由纳米硅酸锆粉和超细的氧化铝粉经烧结复合而成，跟硅酸锆球比较，具有稍低的密度而更高的硬度，特别胜用于硬度和磨蚀性大的物料的分散和研磨。
DURA-37 Zirconia Toughened Alumina (ZTA) ball was formed from the ultra fine alumina powder that toughened by nano zirconia powder. It has a small lower density, but higher hardness than zirconium silicate beads. To disperse and grind the hard and abrasive particle, it can be competent.
