Crystal Structure and Properties of Strontium Cobalt Vanadate Ceramics for Microwave Applications

The development of next-generation cellular communications requires materials with high dielectric properties at high frequencies. SrCoV₂O₇ ceramics, synthesized using Ultra Low-Temperature Co-Fired Ceramic (ULTCC) technology, offer promising characteristics. This study analyzed their crystal structure using X-ray diffraction, SEM microscopy, and energy dispersive spectroscopy. The results confirmed a single-phase monoclinic structure (P 1 21/c 1) with lattice parameters a=6.8360(7) Å, b=14.823(2) Å, c=11.271(1) Å, β=99.4610(5)°. The material exhibits potential for microwave applications, including resonators, antennas, and filters, due to its dielectric properties and compatibility with aluminium electrodes.
