纳米ZrO2粉体的热处理研究
Effect of Heat Treatment on Performance of Nano-zirconia Powders
【摘要】 用共沉淀法在不同热处理工艺下制备纳米ZrO2 粉体。样品的TEM、SAXS、BET和XRD分析结果表明 ,热处理对纳米ZrO2 粉体性能的影响是显著的。结合实验与理论分析 ,得出粉末颗粒长大、团聚的机制与热处理对成分、粒度及微观结构变化的作用
【Abstract】 Series of nano ZrO 2 powders were prepared under different technology of heat treatment.All the results,come from TEM,SAXA,BET and XRD,indicated that the influence of heat treatment on the performance of nano ZrO 2 was notable.Combining the experimental results and theoretical analysis,the mechanism of particles growth and aggregation,and the effect of heat treatment upon the change of composition,granularity and microstructure were obtained.
