Yttria stabilized tetragonal zirconia polycrystals (3Y-TZP) doped with CuO was prepared, to get two compositions, 0.3 and 1 mole fraction CuO, respectively. The dilatometric study of the samples showed sintering to be improved for the samples doped with 0.3 mole fraction CuO, and to be deteriorated for the samples doped with 1 mole fraction CuO. The 1 mole fraction CuO doped 3Y-TZP showed higher tetragonal/monoclinic phase transformation which was accompanied by grain growth. The electrical conductivity decreased with the addition of CuO.

以马来酸酐(MA)、聚乙二醇(PEG)和丙烯酸(AA)等为原料酯化共聚合成一种高分子水泥助磨剂.通过加入不同分子量的聚乙二醇合成一系列侧链长度的高分子助磨剂,研究侧链长度变化对水泥高分子助磨剂性能的影响.结果表明:当PEG分子量为400时,合成的高分子助磨剂助磨效果最佳.对比空白样,水泥比表面积增加32.87％,胶砂3d和28 d抗折强度分别提升17.86％和22.73％;3 d和28 d抗压强度分别提升48.93％和28.32％.
