摘要: Nanosized 10 mol% MgO-doped ZrO2 powder was prepared via coprecipitation, followed by a washing–drying–calcining treatment. Water, ethanol, and mixture of water ethanol (volume ratio 1:1) were, respectively, used as solvents for precipitating washing. These had great influence on the dispersion nanopowders, hence sintering behavior in corresponding ceramics. When used, uniformly dispersed with good property obtained. The function to weaken hydrogen bonds between adjacent nanoparticles that lead formation “hard agglomerates” at first step when hydroxide precipitate just formed.
