Effect of Calcination Kinetics and Microwave Sintering Parameters on Dielectric and Peizo-Electric Properties of(K0.5Na0.5) NBO3 Ceramics

An efficient solid-state approach was established to synthesize (K0.5Na0.5) NbO3 ceramics using calcination kinetics and microwave assisted sintering. Milling of carbonate and oxide raw materials were carried out for 15h to obtain homogeneous nano particles. The crystallite size of 5.30 nm was obtained for the KNN system after calcination through optimized parameters and observed to be stoichio...

Effect of Sintering Temperature on Structural, Dielectric, and Magnetic Properties of Multiferroic YFeO3 Ceramics Fabricated by Spark Plasma Sintering

Based on precursor powders with a size of 200-300 nm prepared by the low-temperature solid reaction method, phase-pure YFeO₃ ceramics are fabricated using spark plasma sintering (SPS) at different temperatures. X-ray diffraction (XRD) and scanning electron microscopy (SEM) reveal that the high-purity YFeO₃ ceramics can be prepared using SPS, while the results from X-ray photoelectron spectrosco...

LOW-TEMPERATURE SINTERING AND MICROWAVE DIELECTRIC PROPERTIES OF (Zn0.65Mg0.35)TiO3-CaTiO3 CERAMICS WITH H3BO3 ADDITION

Low-melting H3BO3, acting as sintering aid, was used to reduce the sintering temperature of 5 wt.% CaTiO3-doped (Zn0.65Mg0.35)TiO3 ceramics. The sintering behaviors, microstructures and microwave dielectric properties with different amounts of H3BO3 addition were investigated. The results showed that H3BO3 additive was very effective for lowering the sintering temperature and improving the bulk...

Effect of V2O5 Doping on the Sintering and Dielectric Properties of M-Phase Li1+x-yNb1-x-3yTix+4yO3 Ceramics

The effect of the addition of V2O5 on the structure, sintering and dielectric properties of M-phase (Li1+xyNb1-x-3yTix+4y)O3 ceramics has been investigated. Homogeneous substitution of V5+ for Nb5+ was obtained in LiNb0.6(1-x) V0.6xTi0.5O3 for x ≤ 0.02. The addition of V2O5 led to a large reduction in the sintering temperature and samples with x = 0.02 could be fully densified at 900oC. The sub...
