Preparation and Property of Mn₃B₇O₁₃Cl Microwave Attenuation Powders

Abstract:

Mn₃B₇O₁₃Cl nanopowders were prepared by sol-gel process. X-ray diffraction (XRD) and Transmission electron microscope (TEM) were utilized to characterize the structure, shape, size of the obtained products. Mn₃B₇O₁₃Cl powder was sintered into a ceramic disk having a diameter of 20mm by Spark Plasma Sintering (SPS). The formation of Mn₃B₇O₁₃Cl nanoparticles and the dielectric properties of Mn₃B₇O₁₃Cl were discussed. The results show that Mn₃B₇O₁₃Cl nanopowders which was obtained after xerogel roasted at 550°C are uniform. The size of the average particle is about 50nm. Mn₃B₇O₁₃Cl ceramic disk has a low dielectric constant and high dielectric loss. It is believed that there is a good application prospect in the field of microwave attenuation.
