The need for sustainable solutions to reduce the carbon footprint of ceramics and glass industry leads towards development new electric current-assisted technologies. Flash sintering-like processes in glasses allow a reduction softening temperature could pave way shaping Herein, we investigated flash transition soda-lime silicate using two different electrode materials, silver, platinum. high d...

This study explored the possibility of using upgraded coal and coke from Indonesian lignite in ironmaking process, specifically pulverized Injection (hereafter, “PCI”) carbon composite pellets material (sintering binder material). The found that (1) injection into blast furnace will have same effect as lime - heavy oil slurry furnace, combined infusion highly volatile matter low ash coal, flash...

The competition between sintering and coarsening is cited by numerous authors as one of the potential factors for explaining ultra-rapid kinetics flash sintering. In particular, surface diffusion a mechanism decreasing driving force changing initial highly reactive microstructures (particle contact) into poorly porous skeleton structures (spherical porosity). We show finite element simulations ...

Novel sintering methods have emerged in the recent past years, which raised great interest scientific community. Relying on electric field effects, high heating rates, use of mechanical pressure, or hydrothermal conditions, they offer fundamental advantages compared to conventional routes like minimizing energy consumption and enhancing process efficiency. This perspective aims at explaining th...

Shrinkage behaviors during shrinkage rate-controlled flash (SCF) sintering were investigated for 8 mol% Y2O3–ZrO2 (8YSZ) when rates varied between 60 and 300 μm/min under alternating current fields of 50 Vrms/cm, 1200 mArms, 1000 Hz at a furnace temperature approximately 870°C. Volumetric power dissipation electrical conductivity shown to exhibit similar dependencies against linear shrinkages e...

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...
