Abstract Dielectric properties in the microwave range of Na3Zr2Si2PO12 ceramics have been rarely studied. The work attempted to develop a new kind of high temperature microwave absorption material. Na3Zr2Si2PO12 ceramics were sintered at different temperatures by a traditional solid-state reaction method for dielectric and microwave absorption properties study. Results showed that the complex permittivity increased to the maximum at 1250 °C then decreased with the elevated sintering temperature. The effective absorption bandwidth (below −5 dB) was obtained in 8.98–12.4 GHz for the ceramic in 2.3 mm thickness and the lowest reflection loss is −12.9 dB at 10.74 GHz, which indicated that Na3Zr2Si2PO12 ceramics would be potential microwave absorption materials by further improvement.

Na 3 Zr 2 Si 2 PO 12 陶瓷在微波范围内的介电特性

摘要 Na3Zr2Si2PO12陶瓷在微波范围内的介电性能鲜有研究。该工作试图开发一种新型的高温微波吸收材料。Na3Zr2Si2PO12陶瓷采用传统固相反应法在不同温度下烧结，用于介电和微波吸收性能研究。结果表明，复介电常数在 1250 °C 时增加到最大值，然后随着烧结温度的升高而降低。厚度为 2.3 mm 的陶瓷在 8.98-12.4 GHz 范围内获得了有效吸收带宽（低于 -5 dB），在 10.74 GHz 处的最低反射损耗为 -12.9 dB，这表明 Na3Zr2Si2PO12 陶瓷将成为潜在的微波吸收材料。改进。
