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)°.

DEVELOPMENT OF A HIGH-FILLED FILAMENT USED IN MFDM TECHNOLOGY

The article describes the research in which a filament highly filled with Co-Cr-Mo alloy powder was developed, the 3D printing process, and the degradation and sintering of the produced samples. The research shows the influence of debinding on the final structure of the material. The research presented in this article allows us to assess the relationship between the particle size of the metal powder and the surface and internal structure of the finished sinters.

DEVELOPMENT OF MAJOLIKA MASS COMPOSITIONS AND TECHNOLOGICAL PARAMETERS OF THEIR PRODUCTION ON ENERGY SAVING TECHNOLOGIES

The sintering regularities of the developed majolica masses compositions on the basis of typicalmass MKL-1 and MK-4K with the addition of broken glass and ceramic bricks wereinvestigated. Theinfluence of these sintering processes additives of the studied mass compositions depending on theircontent and firing temperature is established. A new method of decorating ceramics at the stage of its plastic state was developed. The obtained results will be used to improve the technological processesof obtaining decorative and applied ceramics.
