Global energy consumption increases year after year, causing the depletion of non-renewable sources. According to International Energy Agency (IEA), global demand for electrical is expected increase by 3.3 % in 2024. Therefore, developing new renewable sources urgent, including devices storage and conversion, particularly those based on electrochemical reactions. Water splitting a clean sustainable technology capable facing this issue producing oxygen hydrogen from water electricity....
<title>Abstract</title> In the present work, influence of powder preparation technique on sintering behavior 80 wt.% Al<sub>2</sub>O<sub>3</sub>-18 WC-2 Co composites was investigated. The powders were mixed with a mechanical stirrer for 10 min (MM) and by high-energy milling (HEM) 50 h. They then compacted at 200 MPa sintered in resistive dilatometric furnace 1 h under argon atmosphere heating rate 10°C/min two temperatures (1300°C 1550°C). prepared MM HEM further characterized XRD, SEM...
