Improved sintering characteristics and microwave dielectric properties of 0.02B2O3–0.98SiO2 ceramics by SiO2 nanoparticle additive

Microstructure and Microwave Dielectric Properties of Low-Temperature Sintering Ca5−yLi2yNi4(VO4)6 Ceramics

“…The lattice constant was calculated using software with the Rietveld method to fit the XRD patterns. 16 The microstructural observation of the sintered surface morphology was carried out using scanning electron microscopy (SEM, Philips XL-40FEG) equipped with Energy-dispersive X-ray spectroscopy (EDS), and grain sizes in the samples were obtained from SEM images by the image analysis software.…”

“…Recently, many researchers pay attention to develop genuine lowfiring ceramics [9][10][11][12][13] instead of the low-melting glass addition method. [14][15][16][17][18] Among them, garnet vanadates 19,20 revealed the high potential to fit the most requirements of LTCC applications. The cubic structure Ca 5 Mg 4 (VO 4 ) 6 was first reported by Slobodin et al 21 Yao et al 22 first reported The Ca 5 A 4 (VO 4 ) 6 ceramics sintered at below 900 °C demonstrated good microwave dielectric properties.…”
