| 摘 要： | 用均相钠还原得到的纳米氮化钽粉在1 350℃进行不同时间的热处理,热处理后的粉末制成烧结体并进行阳极氧化过程。通过XRD和场发射扫描电镜分析了粉末的物相结构和形貌,研究了热处理时间和压制密度对氮化钽粉末电性能的影响。结果表明:热处理温度为1 350℃、热处理时间40min、压制密度约4g/cm时氮化钽阳极块体有较高的比容和较低的漏电流常数。 |
| 关 键 词： | 纳米氮化钽粉末 热处理 压制密度 电性能 |

| Abstract: | The tantalum nitride nanopowders synthesized by homogenous sodium reduction were annealed at 1 350 ℃ for different durations.The sintered blocks were electrochemically oxidized.The phase structure and microstructure of sintered powders were analyzed with XRD and FESEM.The effects of annealing time and green density on electrical characteristics of powders were studied.The results show that the sintered anode blocks present high CV and low current leakage when annealed at 1 350 ℃ for 40 min with the green density of the powders of 4 g/cm3. |
| Keywords: | tantalum nitride nanopowders annealing green density electrical characteristics |
