2022年9月26日 · The novel scheelite-structured NaSrLa(MoO4)3 (abbreviated as NSLM) ceramic was synthesized by traditional solid-state process, and its microwave dielectric properties were investigated. X-ray diffraction (XRD) and Rietveld refinement showed that all samples belonged to the tetragonal scheelite structure.

The results show that molybdates (MoO4 -2 ) are coordinated to the carbonyl functional groups of BDC and BHET by urea bonding (-NH-CO-NH-) which is related to their high biocompatibility and high...

2024年10月8日 · SEM analysis showed dense microstructures at 600°C, with an effective sintering range from 550°C to 650°C. Grain sizes varied from 1.472 μm to 4.03 μm, and higher sintering temperatures promoted grain growth, resulting in a more compact microstructure.
