Characterization and Microwave Absorption Properties of Lead-Free Bi0.5(Na0.80K0.20)0.5TiO3 Synthesized by Sol-Gel Method

Abstract: Lead-free Bi0.5(Na0.80K0.20)0.5TiO3 (BNKT) particles were synthesized by using  sol-gel method. The samples were investigated by X-ray diffractometry (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), and vibrating sample magnetometer (VSM). The absorption of microwaves of the lead-free BNKT powders is determined from the magnetic (permeability) and dielectric (permittivity) properties at the frequency range from 2 to 18 GHz. Absorption characteristics of paraffin(wax)-mixed… Show more

“…The BNKT has been shown able to be used as EM wave shielding, or MWA materials. 12) The characterization studies primarily focus on the improvement of the electrical properties as the effect of dopant and co-dopants at A-, Bsite of BNKT or dopant BNKT with different perovskite AABAO 3 . 11) Modifying the BNKT material is a great way to improve dielectric loss and MWA properties, but it does not seem to meet the requirements of practical applications.…”
