dura-60钇稳定氧化锆珠是一种由一级稀土氧化钇稳定的氧化为原料精制而成的四方氧化锆珠(tzp)。珠子内部平均粒径小于0.4μm的四方氧化锆微晶结构致密，确保珠子具有优异的断裂韧性和耐磨性，避免了对所研磨产品的交叉污染。珠子直径从0.1mm到60mm，是现代珠磨机纳米级分散研磨的不错选择。

        dura-60 is one tetragonal zirconia polycristal (tzp) beads, which made from first grade yttria stabilized powder with sintered method. the sizes of internal micro crystals are less than 0.4μm benefit excellent crushing strength and wear resistance, which guarantees cross contamination free to grinded products. it is a top option to deal with the nano fine particle size in modern pearl mills.
