Electrode material for low-temperature co-fired diopside glass-ceramic used for microwave dielectrics was investigated in the present work. Diffusion of silver from the electrode to diopside glass-ceramics degrades the performance of the microwave dielectrics. Two approaches were adopted to resolve the problem of silver diffusion. Firstly, silicon-oxide (SiO₂) powder was employed and secondly c...

Composite material based on Fe3Si micro-particles and Mn-Zn nano-ferrite was prepared using powder metallurgy technology. The sol-gel followed by autocombustion process was used for synthesis of Mn0.8Zn0.2Fe2O4 ferrite. 3 wt.% of mechanically milled ferrite was mixed with Fe3Si powder alloy. Mixed micro-nano powder system was homogenized by the Resonant Acoustic Mixing using ResodynLabRAM Mixer...

Microwave sintering is a method presenting the following advantages for flash sintering: contactless/volumetric heating, and possibility to control heating cycle of microwave power. In this study, transition from typical 100 K/min an ultra-rapid rate 500 studied. The homogeneity hybrid configuration using silicon carbide susceptors tested up stability limit system. We show that zirconia specime...

Aluminium and magnesium matrix composites are attractive lightweight materials with strength surpassing that of the corresponding metals. Recent years have seen extensive research aimed at finding ways to control structure metal obtaining new sets properties. This review aims show field-assisted sintering is a promising approach for powder metallurgy processing aluminium composites. The focuses...
