Abstract

Sr0.2Zn0.8TiO3 (SZT) ternary nanopowders of perovskite structure samples were prepared by conventional solid state reaction technique using ultra-pure metal oxide powders. SrCO3, ZnO and TiO2 powders were used as a source of Strontium, Zinc, and Titanium. The calcination temperature of the samples is 820 °C and sintered at different temperatures ranging from 850 °C to 1000 °C in conventional and microwave furnaces for 2 hours and 30 min., respectively. The synthesized nano-powders were characterized using XRD, SEM, XPS and their dielectric properties were studied by temperature dependent LCR meter. The dielectric constant increases with an increase in sintering temperature until 950 °C and it decreases with a further increase of frequency.

Sr掺杂钛酸锌（Sr0.2Zn0.8TiO3）纳米陶瓷的微波辅助烧结

以超纯金属氧化物粉末为原料，采用常规固相反应法制备了具有钙钛矿结构样品的Sr0.2Zn0.8TiO3 (SZT)三元纳米粉体。SrCO3、ZnO和TiO2粉末被用作锶、锌和钛的来源。样品的煅烧温度为820℃，在850℃~ 1000℃的不同温度下，在常规炉和微波炉中分别烧结2小时和30分钟。采用XRD、SEM、XPS对合成的纳米粉体进行了表征，并用LCR仪对其介电性能进行了表征。在950℃前，介电常数随烧结温度的升高而增大，随频率的增加而减小。
