ZrO_2纳米粒子相结构与等温转变动力学研究

The Study of Phase Composition of ZrO_2 Nano-particles and Isothermal Transformation Dynamics

利用ＤＥＬＴＡ－ＤＳＣ７差示扫描量热仪对ＺｒＯ＿２纳米超微粉进行等温分析测试研究，发现ＺｒＯ＿２纳米粒子在２４０℃等温发生明显的放热转变。

Utilizing DELTA-DSC7 Differential Scanning Calorimeter , an experiment on ZrO_2 nanopar-ticles is made and the obvious exothermic transformation found when the sample is heated isothermal-ly for two hours at 240℃. It is concluded that the exothermic transformation might be the result ofthe phaes transformation of the sample.
