多孔Na3Zr2Si2PO12陶瓷的调控及吸波性能
Research on regulation and wave-absorption properties of porous Na3Zr2Si2PO12 ceramics
摘要
Abstract
In order to maintain excellent properties of wave-absorbing materials in harsh environ-ments such as high temperature and corrosion,the possibility of porous Na3Zr2Si2PO12(NZSP)ceramics being explored as a potential new stealthy material was discussed.Porous NZSP materials were prepared by the traditional solid-state method,and the effects of molding pressure on the microstructure and absorbing properties of porous NZSP were analyzed using XRD,SEM,and a vector network analyzer.It was found that high crystallinity and uniform pore distribution were exhibited by the porous NZSP ceramics when the molding pressure was set at 40 MPa and when sintered at 1 250 ℃ for 4 hours.When the thickness was only 2.1 mm,the reflection loss of-12.6 dB at 10.13 GHz was observed in the ceramic,while the bandwidth of 3.53 GHz(8.76~12.29 GHz)was recorded when the reflection loss was less than-5 dB.Compared to the samples molded at 30 MPa and 50 MPa,better absorbing properties were shown by the porous NZSP ceramics molded at 40 MPa.The results indicate that excellent wave-absorbing properties can be demonstrated by porous NZSP ceramics under suitable molding pressure,thereby verifying their application pros-pects in the field of wave-absorbing materials.关键词
