摘要
以ZrOCl2.8H2O、MgCl2为原料,NH3.H2O为沉淀剂,采用缓冲溶液沉淀法制备MgO-ZrO2前驱体粉体。通过差热分析、X射线衍射、透射电镜等对所得粉体进行测定分析。结果表明:获得了粒径10～20nm淡黄色氧化镁稳定的氧化锆陶瓷(MgO-ZrO2)粉体。在稳定剂浓度为10mol/L时,可获得纯的四方相氧化锆纳米粒子,有望用于口腔齿科材料中。
Nanosized MgO-ZrO2 precursor powders were prepared by buffer-solution precipitation processing using zirconium oxychloride （ZrOCl2·8H2O） and magnesium chloride （MgCl2） as the raw materials, and NH3 -H2O as the precipitation agent. The synthesized powders were characterized by XRD, TEM and DSC-TG. The spherical MgO-ZrO2 particles with an average diameter of 10-20 nm can be obtained. Phase composition analysis indicates that ZrO2 powders are pure tetragonal phase as the concentration of stabilizer is 10 mol/L, which can be potential for dental ceramics application.
