帝诺复合锆珠DURA-32：

DURA-32 复合锆珠由硅酸锆和氧化铝粉经特别的工艺烧结复合而成。相比传统的氧化铝微珠，具有更高的断裂韧性和较低的硬度，是一种代替高岭土球、河砂和铁粒等天然材料研磨介质的经济型和实用型的陶瓷珠。

DURA-32 Zirconia Toughened Alumina (ZTA) bead was sintered from alumina powder and zirconium silicate powder. Compared to the alumina beads, it has a higher fracture toughness and lower hardness. It is an economic ceramic bead to replace Kaolin bead, silica sand and other natural grinding media.
